Whereas, b) STDEV.P, STDEVP, STDEVPA, DSTDEVP will come under Population. The STDEV.P function uses the following formula: In this example, x 1 = 5, x 2 = 1, x 3 = 4, x 4 = 6, x 5 = 9, μ = 5 (mean), N = 5 (number of data points). For this example, variance would be calculated as (0.75^2)*(0.1^2) + (0.25^2)*(0.15^2) + 2*0.75*0.25*0.1*0.15*0.25 = 0.008438.
