0Correlation
A measure of linear relationship between two variables independent and dependent
it is used when and Y both are continuous
Corelation is measure with r (Coefficient of corelation)
r values ranges from
1) r=1 perfect positive relationship
2) r=0 no relationship
3) r=-1 negative relationship
Regression:
Provides the basis for predicting the value of a variable from the values of one or more other variables
used with continuous Y and Continuous Xs or continuous Y and categorical Ys
It is measured with r2 which is known as the coefficient of determination
r2 tells us about the proportion of variation of Y explained by prediction equation
