Name: An introduction to Correlation Coefficients - How are correlation coefficients calculated?
Uploaded: 2020-02-12T00:00:00Z
Description: In the first chapter you will be given a broad overview on the concepts behind correlation as well as some examples. Furthermore, you will walk through the mathematical calculation of the correlation coefficient r, that is the Pearson product-moment correlation coefficient. Finally, there will be a part on the assumptions underlying a typical correlational analysis.

An introduction to Linear Regression
In this first chapter on linear regression, professor Conway will give you an overview on regression; What does it do? What is it used for? You will see how to build and execute a regression model in R, and what the effect is of adding additional regressors.

Linear Regression Models continued
In chapter three you will do the calculation of the regression coefficients yourself in R. Next, there will be a detailed study of the assumptions underlying a linear regression analysis. The end is reserved for Anscombe’s quartet, a famous statistical example that shows you the importance of graphing data before analyzing it.
