This book is not intended to be a substitute for an introductory course or text in statistics. The introductory chapters will briefly cover certain key concepts mostly through readings and videos from external sources. Other concepts that are important to having an appreciation for the theory and use of statistical tests are not addressed. For this understanding, readers are encouraged to pursue an introductory undergraduate course, appropriate MOOC, or careful reading of an introductory textbook.

### Some free general statistics books

Luckily there are free resources available that cover the key concepts in an introductory statistics course. Some of these will be suggested as recommended reading in this book.

### Online Learning Modules and Massive Open Online Courses (MOOC’s)

Online learning modules and online courses offer another alternative to learning basic statistical concepts, programming in R, or advanced statistical techniques.

*Swirl*

Swirl has free, brief lessons for beginners to R programming and analysis. Topics include R programming, data analysis, data visualization, data manipulation, statistical inference.

* *

*DataCamp*

DataCamp has short online modules covering topics such as an introduction to R, data manipulation, data visualization, and statistics with R. Limited parts of several courses are free. For the complete courses, there is a subscription charge. There is a discount for students.

*Coursera*

Coursera hosts MOOC’s from various universities on a range of academic topics, including introductory statistics using R. Courses are free, though there is an option to pay for a certificate in a data science specialization.

*edX*

edX also hosts free MOOC’s from universities on a variety of topics, including a course on introduction to R programming.

*Udemy*

Udemy hosts relatively inexpensive online courses on a variety of subjects, including programming and statistics with R. Some are free.
