(Sum of D2) ED2
Keep about 4 decimals to subtract from 1. If the fraction simplifies to a number greater than 1, you will have a negative value for rho, but it should still be somewhere between -1 and 1. Anything outside of the range of -1 to +1 indicates a calculation error!! 6* D² rho = p = rs = 1- 6* ?D2 n(n²-1) 1- n³ - n Use this table to show your step-by-step calculation of rho. 6*ED² n(n²-1) or (n³-n) 6-202 n³-n 1- 6* D² n³-n rho (Answer rounded to 2 decimals)
