please tell me wheather the 'cofficient of correlation' is the measurement of central tendency or variation
Coefficient of correlation' gives how much a value is close to the mean value.
It range from -1 to 1, so the value is close to 1 or -1, then there is strong linear relationship, which means it is close to most of the values. So it gives the detail about the amount of variation.
