Answer #1

The following are the main properties of correlation.

1. Coefficient of Correlation lies between -1 and +1 that is -1 ≤ r ≤ 1

2. Coefficients of Correlation are independent of Change of Origin

3. Coefficients of Correlation possess the property of symmetry

4. Coefficient of Correlation is independent of Change of Scale

5. The correlation coefficient is symmetrical with respect to XX and YY  i.e.
6.he correlation coefficient is the geometric mean of the two regression coefficients
