What is Data Science?
Data science is an interdisciplinary field that uses scientific methods, algorithms, processes and systems to extract knowledge or insights from data in various forms, both structured as well as unstructured, similar to data mining.
It is about using data to generate insights that can be used to improve decision-making. Data science encompasses a wide range of activities, from data cleaning and wrangling to advanced statistical modeling and machine learning. It is an interdisciplinary field that combines computer science, statistics, and mathematics.

After enrolling in the course, you can consult the study materials attached at any time, and you can take the quiz at the end to gauge your understanding.
- Statistical Methods for Decision Making: Your understanding of sampling, normal distributions, hypothesis testing and its various forms, type 1 and type 2 errors, chi-square testing, and ANOVA is the goal of the Statistical Methods for Decision Making course. Through illustrated examples and examples that have been solved, the course will solidify the concepts in your mind.
- Statistics for Data Science: This statistics for data science course will provide you with insights from a novice’s point of view and introduce you to various aspects of statistics and concepts needed to address a variety of data science problems. You will also comprehend a variety of topics, including distributions and plots, univariate statistical plots and usage, bivariate and multivariate statistics, probability, the addition and multiplication rule, the Bayes theorem and using it to solve problems, the normal and binomial distributions, the Poisson probability function, and the normal distribution function.
- Data Science with Python: The fundamentals of Python programming and the various packages required for data science are covered in this course on Python with Data Science. Additionally, univariate, bivariate, and multivariate statistics, as well as statistical distributions, are covered. The following lesson will cover regression, a fundamental data science technique. You will learn about the different types of regression and how to use them to solve business problems. You will solve problems from the real world throughout the entire course, which is experiential and hands-on.
- Data Visualization With Power BI: This course is designed for users who want to learn how to create and interpret data visualizations using Power BI. The course covers basic and advanced topics, including how to create custom visualizations, work with different data sources, and use Power BI to make data-driven decisions. By the end of the course, users should be able to create and interpret data visualizations to help them understand and analyze data.
- Data Visualization using Tableau: This course will teach you how to use Tableau to create powerful data visualizations. You’ll learn how to connect to different data sources, how to create different types of visualizations, and how to interact with your data. By the end of the course, you’ll be able to create your own data visualizations that can help you better understand your data.
- R for Data Science: With the help of a few real-world examples, this course will introduce you to R programming for data science. The course will concentrate on the components and capabilities of R that you can use to complete Data Science tasks. It will start with an introduction to the fundamentals of R programming and then guide you through the course’s first half by explaining data structures, built-in functions, user-defined functions, and flow control statements. The second part keeps you interested by discussing data manipulation and visualization using factors and data frames in R.
- Predictive Modeling and Analytics – Regression: The purpose of Predictive Modeling and Analytics – Regression is to answer your questions about the topic and aid in your understanding of the fundamental ideas. You learn about simple linear regression, best fit line, multiple linear regression, linear regression assumptions, multicollinearity, fit-R square, and variables concepts in this course, which also introduces you to predictive modeling. Later on in the course, it talks about classification methods that use predictive modeling.
