What is the variance of 5, 13, 32, 37, 49, 51, 63

s2 ≈ 438.2383

Answer:Variance: 438.2380952380951

Step-by-step explanation:First, I added up all of the numbers:5 + 13 + 32 + 37 + 49 + 51 + 63 = 250

I squared the total, and then divided the number of items in the data set250 x 250 = 62500

62500 / 7 = 8928.57142857143

I took my set of original numbers from step 1, squared them individually this time, and added them all up: (5 x 5) + (13 x 13) + (32 x 32) + (37 x 37) + (49 x 49) + (51 x 51) + (63 x 63) = 11558

I subtracted the amount in step 2 from the amount in step 3:11558 - 8928.57142857143 = 2629.4285714285706

I subtracted 1 from the number of items in my data set:7 - 1 = 6

I divided the number in step 4 by the number in step 5:2629.4285714285706 / 6 = 438.2380952380951

This is my Variance!
