Question

any three properties of correlation coefficient​

Answer 1

Answer:

Properties of the Coefficient of Correlation

The correlation coefficient is symmetrical with respect to X and Y, i.e. rXY=rYX.

The correlation coefficient is the geometric mean of the two regression coefficients r=√bYX×bXY or r=√b×d.

The correlation coefficient is independent of origin and unit of measurement, i.e. rXY=rUV.
