In some places the variance is defined as the sum of the squared differences of each data point value from the mean, divided the N - 1, and other places it's divided by N:
- The variance is the average number of these squared differences:
(2061.16+1128.96+3672.36+2440.36+338.56+0.16+384.16) / 7 = 1432.2
Shouldn't it be / 6 for the variance?
Also here: with N in the denominator?
