Explanation / Answer

Class Width = (Max Value- Min value)/No of classes

a) Max Value = 79

Min Value = 11

No of classes = 7

Class Width = (79-11)/7=68/7=9.7=10 (On rounding)

Class Width = 10

b) Max Value = 51

Min Value = 4

No of classes = 6

Class Width = (51-4)/6 =47/6 = 7.83 = 8(On rounding)

Class Width = 8

c) Max Value = 49

Min Value = 3

No of classes = 6

Class Width = (49-3)/6 = 46/6 = 7.667 = 8(On Rounding)

Class Width = 8

d) Max Value = 51

Min Value = 2

No of classes =5

Class Width = (51-2)/5 =49/5= 9.8 = 10(On Rounding)

Class Width = 10
