Lesson 4.2.2 – How can I measure my linear fit? - Correlations Objective – I will be able to calculate the Correlation Coefficient (r) and use it to describe the association between two variables. Quote of the Day – “Believe you can and you are half way there”: Theodore Roosevelt

Correlation Coefficient (r): A measure of how much a data set is “scattered” around a Least Squares Regression Line (LSRL). A strong correlation will have an r value close to 1 or -1 with no correlation at an r value of 0.
