17.19


First match scores: 33, 24, 19, 21, 41, 39, 37, 47, 38, 29 and 26
Total Numbers = 11
Sum = 354
Mean (Average) = 32.18
Population Standard Deviation = 8.61


Second match scores: 13, 44, 19, 93, 41, 76, 33, 44, 29, 11 and 7
Total Numbers = 11
Sum = 410
Mean (Average) = 37.27
Population Standard Deviation = 25.80

The difference between Population Standard Deviation: 25.80-8.61=17.19
