Math for data science

Data science is a field that requires the use of mathematics in order to extract insights from data. 

The world is changing quickly with the advancements in technology. With the use of data science, businesses and individuals can make better decisions and gain a competitive edge.

This article will discuss some of the math topics that are important for data science. It will also provide some examples of how they are used in data science.

Math Topics

Basic Statistics: The most basic form of statistics is to calculate the mean, median, mode, and standard deviation.

Probability: Proportions are usually expressed as a percentage or a fraction.

Functions: Functions are used to describe relationships between different variables or to find patterns in data sets. They can be linear or nonlinear functions.

EDA (Exploratory Data Analysis) in Data Science

Exploratory Data Analysis is the process of exploring and visualizing data to understand its behavior in order to make informed decisions.
EDA is a useful tool for data scientists because it helps them to discover patterns, outliers, and trends in their data. It also helps them identify anomalies and missing values.

It is not easy to examine a column of numbers or an entire spreadsheet and determine essential aspects of the data. It may be difficult, boring, or overwhelming to extract insights by looking at basic numbers. In this case, exploratory data analysis techniques have been developed to help.

EDA has become an integral part of many data science projects because it provides insight into the behavior of the data and helps make informed decisions about what to do with it.

There are two ways to categorize exploratory data analysis. The first point is that each method is either non-graphical or graphical. Second, each method is univariate or multivariate in nature (usually just bivariate).

Data scientists use EDA to make sure that the results they give are correct, can be correctly interpreted, and can be used in the business contexts they want.

What Is Data Wrangling?

➤ Gathering of data from diverse sources to reveal “deeper intelligence.”

➤ In a timely manner, deliver reliable, actionable data to business analysts.

➤ Reduce the amount of time it takes to collect and organise disorderly data before using it.

➤ Allow data scientists and analysts to concentrate on data analysis rather than data wrangling.

The Basics of Data Wrangling

Data Acquisition: Find and acquire access to the data included in your sources.

Joining Data: Combine the modified data for further use and analysis.

Data Cleaning: Redesign the data in a usable and organized manner and remove any bad data.

Hypothesis testing in data science

Hypothesis testing is a statistical technique that helps to determine the probability of an event. It is used in many fields, especially in data science.

Hypothesis testing is a method in statistics that helps us decide whether our data is valid and reliable.

It is important to understand the basics of hypothesis testing so that you can conduct your own hypothesis tests in your data science projects.

Parameters & Statistics In Hypothesis testing

A parameter is a description of a population in statistics, whereas a statistic is a description of a small subset of a population (sample). 

If you question everyone in your class (the population) about their average height, you’ll get a parameter, which is a genuine representation of the population because everyone was asked. 

This information becomes a statistic if you wish to determine the average height of people in your grade (population) based on the information you have from your class (sample).

Parametric tests are hypothesis tests that include a specified parameter. The population in parametric testing is assumed to have a normal distribution (e.g., the height of people in a class).

The Basic Steps of Hypothesis Testing

There are many steps to testing a hypothesis, such as

1. Null & Alternative hypothesis

The null and alternative hypotheses are two statements that are mutually exclusive. The null hypothesis states that no impact or difference exists. The alternative hypothesis is what you want to prove.

2. Selection of an appropriate test statistic

To put your assertions to the test, you must select the appropriate test or test statistic. The t-test, z-test, and F-test are all commonly used tests that assume a normal distribution. In business, however, a normal distribution is rarely assumed. 

3. Data Collection

A random sample of the true population of interest is required to conduct a hypothesis test. To eliminate bias or undesired consequences, the sample should be chosen at random.

Data Visualization In Data Science

Data visualization is an important part of data science and helps to bring the data to life. It can help a person understand the data better by using visual representations.

Data visualization is also a key component of Big Data and it helps in making sense of large amounts of information. Data visualization can be used in various ways, such as creating interactive dashboards, creating infographics, and presenting results in a more attractive way.

It is a tool that can be used by data scientists to present their results or insights, as well as for business analysts, marketers, and journalists.
Data Visualization is required for understanding datasets that are too large or too complex for human beings to analyze on their own.

What are the steps followed in Data Visualization?

The following are some of the most important steps in of Data Visualization in Data Science

Data Cleaning

Data Science Visualization can help in the detection of null values in large datasets by representing them differently. This reduces the load of finding mistakes before dealing with data for professionals.

Data Exploration

Data visualization involves the creation of visualizations that can help people find information or help them identify patterns in their own data.


Machine Learning Models for Predictive Analysis are created by Data Scientists. To improve these models, they are trained with enormous datasets. When the models are being trained, the results are analyzed using Data Visualization Tools to see how well they are performing and where they are lacking.

Identifying Trends

Real-time data is sometimes used by data scientists and data analysts to derive relevant trends. Real-time data is challenging to examine since it is always changing. For a better understanding, the data might be displayed using charts and graphs.

Data Preprocessing In Data Science

Data preprocessing is the first step in data science. It includes the collection of raw data, cleaning it up for analysis, and transforming it into a form that can be analyzed. There are many steps involved in preprocessing, which include:

  • Collection of raw data
  • Cleaning up raw data for analysis
  • Transforming raw data into a form that can be analyzed

Probability For Data Science

Probability is a branch of mathematics that deals with the analysis and application of random variables. It can be understood as a measure of the chance that something will happen.

It is used in statistics, game theory, and other fields to quantify the chance that an event will occur.

The most important part of data science is data analysis, which includes probability for data science and statistical inference.
Probability is not just about understanding what is happening, but also about calculating and understanding how likely it is to happen.

The formula for probability is,

P(A) = Number of favorable outcome / Total number of favorable outcome

Data Science Process/Methodology

Data Science is a process that helps individuals and organizations extract, clean, analyze and visualize data.

The primary goal of data science is to find patterns in large amounts of data. It can also be used for forecasting future outcomes or predicting the behavior of individuals based on their social media posts or credit card purchases.

The procedure for discovering solutions to a specific problem is referred to as “Data Science Methodology.” This is a cyclic process that goes through a critical phase, directing business analysts and data scientists to take the proper actions.

Understanding Of The Business

Any problem in the business domain must be thoroughly understood before it can be solved. Understanding business creates an advantage, which makes it easier to solve problems. We should have a clear understanding of the problem we are attempting to solve.

Understanding The Analytic Process

The analytical method to use should be determined based on the given business information.
There are four types of approaches: descriptive (current status and information given), diagnostic (a.k.a. statistical analysis, what is occurring and why it is occurring); predictive (it predicts trends or future event probability), and prescriptive ( how the issue should be resolved in reality).

Requirements For Data

The above mentioned analytical process identifies the required data content, formats,    and sources. During the data requirements process, one should find the answers to questions like “what”, “where”, “when”, “why”, “how” and “who”.

Data Collection

The data collected can be retrieved in any format. So, the data acquired should be validated in keeping with the approach chosen and the desired output. As a result, if more data is needed, it can be gathered or the useless data can be discarded.

Understanding the Data

“Is the data collected representative of the problem to be solved?” is the question that data understanding answers. Descriptive statistics determine the measures that are applied to data in order to determine the content and quality of the data. This step could result in a reversion to the prior stage for correction.

Data Preparation

Let’s look at two analogies to help us understand this topic. The first is to wash freshly picked vegetables, and the second is to just take the desired foods to eat from the buffet. Vegetable washing denotes the removal of dirt, i.e. unwanted items, from data. Noise reduction is carried out here. Putting just eatable items on the plate, that is, if we don’t need specific data, then we should not consider it for further process. This whole procedure includes transformation, normalization, etc.


Modeling determines whether the data that has been prepared for processing is suitable or if it requires additional finishing . The goal of this phase is to create predictive and descriptive models.


Model evaluation is done during model development. It examines the model’s quality as well as whether it fits the business’s needs. It goes through a diagnostic measure phase (to see if the model is working as intended and if any changes are needed) and a statistical significance testing phase (ensures proper data handling and interpretation).


The deployment phase determines how well the model can handle the external environment and some models perform better than others.


Feedback is a necessary function that helps in the development of the model as well as accessing its performance and influence. The steps involved in feedback include defining the review procedure, keeping track of the record, measuring performance, and reviewing and modifying the results.

Data Science Life Cycle

The data science life cycle is a model that describes the process of analyzing and transforming data into insights.

The Data Science life cycle is a series of steps that can be iterative and important to complete a project or data analysis. These steps can be unique, but most projects follow the same general steps.

The data science life cycle includes different stages. These stages are: data collection, preparation, modeling, deployment, and monitoring. 

With the help of these stages, it becomes easy for teams to identify opportunities and make changes in their business models.

The 6 Stages of the Data Science Life Cycle

Framing The Problem

The Problem Framing Stage is the first step in the Data Science Life Cycle. The goal of this part is to identify the problem that you want to solve and understand it.
In order to frame the problem, it is important to understand what business or research question you are trying to answer. You should also know who your audience is and how they will be impacted by your solution.

Collecting Data

After defining the problem we’re attempting to solve, we must gather data that can be used in the next steps of the problem-solving.

Here, data scientists collect and organize data. 

The Collecting Data Stage is a very important part of the Data Science Life Cycle where it is decided what type of data to collect and how to collect it.

This process can be tedious and time-consuming, but it’s important to get insights from the data gathered from various sources.

Data Processing

We need to process the data after gathering it from reliable sources.

The processing stage in the data science life cycle is where all of the raw data is transformed into a format that can be used by analysts to generate insights. This stage includes cleaning, filtering, and pre-processing.

Data Exploration

Data exploration is a step where you get to know the data before working with it. Large datasets are prepared for deeper, more structured analysis through surveys and investigation.

At this stage, we collect as much information about our dataset as possible. We also need to find out what questions we want to ask in order to make sense of our dataset.

The purpose of the data exploration step is to ensure that we can discover patterns from our data that will help us solve our problem.

Analyzing the Data

At this stage, we decide what we want to analyze and what the suitable methods are for it.
Data analysis is where we make sure that our data is in order and we are ready to make a decision or prediction with it. This stage includes checking if there are any missing values or outliers in our dataset.
In this step, we try to get a deeper understanding of the data we have collected and processed. We use statistical and numerical methods to draw inferences about the data and to identify the relationship between multiple columns in our dataset.

We can also use visualizations to better understand and summarize the data using images, graphs, charts, plots, etc.

Consolidating Results

The Consolidating Results stage is the last step in the Data Science Life Cycle. It is where the data scientist takes all of the analysis and results that they have generated and presents them in a way that is meaningful to others. They are also responsible for packaging their findings into a report, presentation, or publication.

Data science is an important part of many different industries, such as healthcare, finance, marketing, etc. With the data science life cycle being so crucial to these industries, it’s important to know exactly what it entails and how one can go about completing this process.

Clustering In Data Science

Clustering is a data science technique that groups similar data points together. This can be done by comparing the similarities of the data points and finding patterns in them.
Clustering is one of the most popular techniques used in data science and has been applied to many different industries with diverse applications such as finance, marketing, social media, and healthcare.

Types of Clustering

Clustering is classified into two categories

Hard Clustering

In hard clustering, each data point is either totally or partially associated with a cluster.
Let’s say you have a data set of 100,000 students. You want to cluster them into a smaller number of groups. In this case, you would use the hard clustering technique to find the best cluster size for your data set.

Soft Clustering

Instead of assigning each data point to a separate cluster, soft clustering assigns a chance or likelihood of that data point being in those clusters.

The idea is that, when you have a lot of similar content, the algorithm can group them together and then search for the most relevant one.

Algorithms for clustering

We will also discuss the many types of algorithms that may be used for clustering and how they can be used in different scenarios.

1. Connectivity models

The essential notion of connectivity-based clustering, also known as hierarchical clustering, is that things are more related to neighboring objects than objects further away. These algorithms use distance to connect “objects” to generate “clusters.”

2. Centroid Models

The most common type of clustering is centroid-based clustering. 

These methods divide data points into groups based on several centroids in the data. Based on its squared distance from the centroid, each data point is assigned to a cluster. This is the most popular clustering technique.

3. Distribution Models

With a distribution-based clustering method, all data points are considered to be part of a cluster based on how likely they are to be in that cluster.

It works like this: if there is a center point, the further a data point is from the center, the less likely it is to be a part of that cluster.

If you’re not sure how your data will be distributed, you should use a different type of algorithm.

4. Density Models

These models look for locations in the data space with varying densities of data points. It isolates various density regions and groups the data points inside these regions into clusters. DBSCAN and OPTICS are two popular density models

Popular Algorithms Used In Data Science

These models look for locations in the data space with varying densities of data points. It isolates various density regions and groups the data points inside these regions into clusters. DBSCAN and OPTICS are two popular density models

1. Linear Regression

Linear regression is a statistical technique for estimating and predicting a continuous outcome based on a set of independent and dependent variables. The technique fits a linear equation using the least-squares method to data points in an x-y scatter plot.

2. Logistic Regression

Logistic regression is one of the most commonly used data science models. It is mainly used to predict continuous outcomes from a set of predictor variables.

Logistic regression is a powerful tool that allows you to understand your data better and make predictions with more accuracy.

Logistic regression is a type of statistical algorithm that can be used to predict the probability of an event happening. It is also called a logit regression or a logit model

Ronald Fisher developed this model in 1938 and it has been widely used in many fields such as marketing, forecasting, and economics.

3. Decision Trees

Decision trees are a type of data science model used to predict the outcome of a given event. They are widely used in the industry due to their simplicity and accuracy.

Decision trees are widely used in many industries, such as marketing, finance, and healthcare. They are a great tool for making predictions about future events.

4. Random Forest

A Random Forest is a machine learning algorithm that can be used to build decision trees. It is one of the most popular algorithms in data science. This algorithm has been used in many different fields, including marketing, finance, and biology, to predict customer behavior or analyze a particular situation.

The Random Forest model is also known as the Random Decision Forest (RDF). They are used to find patterns in large datasets by building decision trees that have a large number of samples in them.

It has been seen that random forest performs better than other models in predicting outcomes with more complex structures, such as those with categorical variables or multiple dependent variables.

4. Regression Analysis

Regression analysis is a statistical technique that predicts the values of one variable based on the values of other variables.

It is one of the most important techniques that data scientists use in their work. It helps them to understand how a variable changes with time and how to make predictions about it.

Regression analysis is also used in business analytics, marketing, and healthcare to predict customer behavior and trends.

Components Of Data Science

Data science is the process of identifying patterns in data. Insight can be extracted from these patterns and used for business intelligence or the development of new product features.

Both of these data science project outcomes can be valuable to product teams wanting to differentiate their offers in the market and give more value to customers. But before your team can start to use data science, they need to know about key components of data science.

Data Science has following four main components

1. Data Strategy

Developing a data strategy simply entails deciding what data you’ll collect and why. 

If you run a business, you have data., but data simply won’t help you optimize and develop it. If you want to turn data into value, you’ll need a data strategy.

The tools, methods, and rules that specify how to manage, analyze, and act on company data are referred to as data strategy. A data strategy can assist you in making data-driven decisions. It also helps in the security and compliance of your data.

2. Data Engineering

Data engineering is a branch of data science that focuses on practical data collecting and analysis applications. Data engineers are responsible for the design, analysis, and management of these systems.

Data engineering is a very important part of data science. Big data applications and harvesting are the focus of data engineers. They don’t perform a lot of analysis or experiment design in their job. 

They could be experts in the following areas:

  • ➤Architecture of the system
  • ➤Programming
  • ➤Configuration and design of databases
  • ➤Configuration of the interface and sensors

A data engineer is more knowledgeable about distributed systems and is a better coder than a data scientist. Data engineering requires a deep understanding of a wide range of data technologies and frameworks, as well as how to combine them to make solutions that support business processes through data pipelines.

3. Data Analysis

The process of analyzing, cleansing, manipulating, and modeling data with the objective of identifying usable information, informing conclusions, and assisting decision-making is known as data analysis.

Data analysis has many facets and methods, including a wide range of techniques.

Data analysis is important in today’s business environment because it helps businesses make more data driven decisions and run more efficiently.

This is the process of making sense out of a set of collected data by identifying patterns and relationships within them. It also entails generating predictions, drawing conclusions, and creating visualizations based on these findings.

4. Data Visualization

A graphical representation of information and data is referred to as “data visualization.”
Data visualization techniques make it easy to identify and comprehend trends, outliers, and patterns in data by employing visual elements like charts, graphs, and maps.
In today’s world, we have a lot of data in our hands, so data visualization tools and technologies are essential for analyzing huge volumes of data and making data-driven decisions.
Data visualization is one of the most important skills for data scientists. They need to be able to visualize their data in a way that makes it easy for non-data scientists to understand.
Data visualization can be done by using either 2D or 3D graphs, charts and maps.

It’s used in a variety of situations, including:

Visualize phenomena that you can’t see immediately, such as weather patterns, medical issues, or mathematical correlations.

Types Of Data In Data Science

Working with data is essential because we must determine what type of data we have and how to use it to get useful results.

It’s also crucial to understand which type of plot is best for which data category; this helps with data analysis and visualization.

Working with data requires strong data science abilities as well as a thorough awareness of various sorts of data and how to work with them.

In research, analysis, statistics, and data science, various forms of data are used. This information assists a business in analyzing its operations, developing strategies, and establishing an effective data-driven decision-making process.

1. Nominal Data

Nominal data is a good source of data for analysis. However, it is not the most suitable source of data for many applications.


The main challenge with nominal data is that it has a low level of statistical significance. This makes it difficult to draw conclusions from the results. The problem can be solved by using other sources of nominal data such as categorical or continuous variables (e.g., grades).

2. Ordinal Data

Nominal data is a good source of data for analysis. However, it is not the most suitable source of data for many applications.


The main challenge with nominal data is that it has a low level of statistical significance. This makes it difficult to draw conclusions from the results. The problem can be solved by using other sources of nominal data such as categorical or continuous variables (e.g., grades).

3. Discrete Data

The word “discrete” refers to anything different or separate. The discrete data is made up of values that are whole numbers or integers.
For example, discrete data can be the overall number of students in a class, which doesn’t have a decimal or fractional value.
The discrete variables can be counted and have finite values. However, they can not be subdivided.
A bar graph, number line, or frequency table are commonly used to illustrate discrete data.

4. Continuous Data

Data scientists are using continuous data to solve problems in the fields of machine learning, statistics, and data science.

Fractional numbers are used to represent continuous data. It could be the Android phone’s version, a person’s height, the length of an object, and so on. Continuous data is information that can be broken down into smaller parts. Any value within a range can be assigned to the continuous variable.

The main distinction between discrete and continuous data is that discrete data includes integers or whole numbers. Continuous data, on the other hand, uses fractions to store different kinds of information, like temperature, height, width, time, speed, and so on.

Continuous Data Examples :-
