Question

Find the range and variance and standard deviations of 11 jersey numbers ( 56,73,92,39,17,79,80,28,11,34,49)

Answer 1

Given 11 data values are,

56, 73, 92, 39, 17, 79, 80, 28, 11, 34, 49

Here, minimum value = 11 and maximum value = 92

Range = maximum value - minimum value = 92 - 11 = 81

Range = 81

Using, Excel we get,

Sample variance = 753.6182

Sample standard deviation = 27.4521

Population variance = 685.1074

Population standard deviation = 26.1746
