Correlation Analysis
Method to determine the direction/strength of the linear relationship b/t two quantitative vars (X and Y)
- use RHO parameter
- p = 0 , X and Y UNCORRELATED
- p > 0, POSITIVE CORRELATION b/t X & Y
- p < 0 , NEGATIVE CORRELATION b/t X and Y
- X increase, y decrease
- p < 0 , NEGATIVE CORRELATION b/t X and Y
- p > 0, POSITIVE CORRELATION b/t X & Y
- p = 1 or p = (-1) PERFECT CORRELATION
- p = 0 , X and Y UNCORRELATED
- Uncorrelation doesn't imply no relationship, only no positive relationship
- use RHO parameter
