How You Can Learn Data Science for Free in 2022?

29-Jan-2022

The term "data science" refers to a collection of methods, tools, and machine learning techniques. The main purpose is to find hidden patterns in unprocessed data. The demand for data scientists is at an all-time high in firms that rely significantly on data. A data scientist is concerned with extracting insights from raw data and combining them with various machine learning techniques to predict a future occurrence. The prospect of a data science career is exciting as well as rewarding, and there is no better time than now to get started if you want to be a successful data scientist.

Online courses can be a terrific way to learn about the important stuff promptly (and on your own time), from technical abilities like Python or SQL to data analysis and machine learning. However, you may need to make a financial investment to acquire the actual deal.

Whether you're searching for a serious deep dive or just a casual overview, we've highlighted some of the highest-rated and most popular free, short, and comprehensive courses you can take within the domain of data science below.

Learn Data Science for Free - Best Courses

Let's look at what order you should learn these topics in and what free resources you may use to learn them.

Beginner's Machine Learning Course (YouTube -FreeCodecamp)

It might surprise you to learn that this course was created by a child. The substance and visibility you'll get here, on the other hand, are unrivaled. On FreeCodecamp's YouTube channel, this course is offered for free. Fundamentals of machine learning, linear and logistic regression, decision trees, boosting, hierarchical clustering, and other topics are all thoroughly covered.

Python - Data Science Programming Language

This course, sponsored by the University of California, San Diego, introduces you to a variety of sophisticated and open-source tools, including Python, Git, Pandas, and others. After completing this course, you will be able to make the most of enormous datasets by importing data, exploring it, learning from it, analyzing it, and visualizing it using Python tools.

An Overview of Data Science

As the name implies, this course will teach you everything you need to know about the fundamentals of data science. This online data science course covers everything from defining data science to an introduction to regression, R and Python, and understanding applications.

Tools for Data Science

Without the use of appropriate tools to make the most of data, data science is meaningless. This online data science course will teach you how to use data science tools such as Jupyter Notebooks, the RStudio IDE, and Watson Studio.

Methodology of Data Science

One of the primary issues that businesses encounter is a lack of knowledge of the questions being asked and how to effectively apply the data to the topic at hand. This is the audience for the Data Science Methodology course. The course will teach you the key steps in approaching a data science problem.

Application and Framework of Hadoop

This online data science course is for you if you want to learn the fundamental techniques for wrangling and interpreting huge data. You'll be able to walk through real-world examples using the Spark and Hadoop frameworks. This online data science course will walk you through the fundamentals of Hadoop architecture, execution environment, and software stack over the course of five weeks.

R Basics in Data Science

This online data science tutorial will teach you the fundamentals of R programming. The course will introduce you to R's functions and data types before moving on to how to work with vectors and when to employ advanced functions like sorting. Because data scientists are also involved in data visualization and wrangling, this course is appropriate for them.

High Dimensions of Data Analysis

The course begins by leading to an extensive explanation of machine learning. You'll learn how to apply machine learning to high-throughput data as you go along. It's an intermediate-level course that covers topics like factor analysis and multiple dimensional scaling plots, among other things.

Codecademy's Data Science Path

The Codecademy routes are fantastic for a variety of reasons. For starters, they dive in-depth and in an organized manner into a given sector, providing you with all of the necessary tools. Two, they're extremely practical, allowing you to apply what you've learned to real-world scenarios and tasks. Furthermore, they are created by genuine engineers in this case, a real data scientist who are experts in their field.
