What size would you recommend for the class interval if the set of the data consists of 45 observations between0 and 29?

No of Observation = 45

Higest value = $29

Lowest Value = $0

K = ?

i = ?

a) 1st we find out K

K= 2x2x2x2x2x2 =2^6

Xlasses = 6

b) find out (i) = H-L/K = 29-0/6 = 29/6

i= 4.833
