# Best Books for Data Science in 2020 for all Level of People

Statistical methods play a key role in **data science**. There are some excellent introductory and advanced level textbooks for data scientists which explains how to apply various statistical methods to data science, how to avoid their misuse and gives you advice on what's important and what's not.

Here you will get some of the best books for data science in 2020. Check them out and find the perfect ones for you!

This is a great informative book for those who are newer, and a little more experienced. This is a good introduction to practical statistics which provided a number of excellent practical logical explanations. People who are interested in statistics and data science find this book very helpful.

**Charles Wheelan clarifies key concepts such as**

- Inference
- Correlation
- Regression analysis
- Randomized experiments
- Hypothesis tests
- Issues related to confidence level and p-value.

The writer reveals how biased or careless parties can manipulate or misrepresent data. He again shows us how brilliant and creative researchers are exploiting the valuable data from natural experiments to tackle thorny questions.

**Statistics with R **is a great book for beginning data analysis. A beginner will quickly be able to use data analysis tools such as ggplot2 and dplyr etc. Students and working professionals find this book very informative. It provides an integrated treatment of statistical inference techniques in data science using the R statistical software.

So we can say that this is an awesome resource for all levels who want to reach the depth of statistics and data science.

Statistics: The Art and Science of Learning from Data includes a chapter summary and chapter problems at the end of every chapter. It includes an online review for a better understanding of the topics. It also explores data with graphs and numerical summaries, the association between two categorical variables, two quantitative variables, good and poor ways to sample and experiment, probability distributions and much much more.

This book is divided into four parts. These are

- Gathering and exploring data
- Probability, probability distribution, and sampling distributions
- Inferential statistics
- Analyzing association and extended statistical method

It’s important for students to learn and analyze both quantitative and categorical data. Concepts are introduced first with categorical data, and then with quantitative data.
