Course Description

If you have ever taken a math or statistics class, you’ve probably heard the old adage "Correlation does not imply causation". The first part of this course explores this further, and will offer a broad overview on correlational analysis. In the second part you will leave descriptive statistics behind, and dive into regression, prediction and inferential statistics.

1An introduction to Correlation Coefficients Free

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.

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.
