Explanation / Answer

57 64 54 36 71 91 55 92 6 43 49

Maximum value = 92

Minimum value = 6

Range = Maximum value - Minimum Value

= 92 - 6 = 86

Mean = (57 + 64 + 54 + 36 + 71 + 91 + 55 + 92 + 6 + 43 + 49) / 11

= 56.2

Sum of squares of differences = (57-56.2)2 + (64-56.2)2 + (54-56.2)2 + (36-56.2)2 + (71-56.2)2 + (91-56.2)2 + (55-56.2)2 + (92-56.2)2 + (6-56.2)2 + (43-56.2)2 + (49-56.2)2 = 5933.64

=> Sample variance = 5933.64 / 10 = 593.364

Sample standard deviation = 593.364 = 24.36 = 24.4
