Linear Relationship

A relationship between two variables where the change in one variable is directly proportional to the change in another variable.

Pearson Correlation

Covariance

A measure that indicates the extent to which two variables change together; if the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the lesser values.

Reject Null Hypothesis
