This course is an introduction to the topic of linear regression and how to implement them using the R programming language. Linear regression models are used in machine learning, so this course serves as an introduction to the topic as well. R is used by professionals in the Data Analysis and Data Science fields as part of their daily work.

In this course, you will learn how to make linear regression models using R. In addition to learning how to make the model, you will also learn how to interpret it.
