How can we find out class - width or class size ?

for eg. Find the class size foe class interval from 20-29 !

Asked by Payal Gupta(SALWAN PUBLIC SCHOOL) , on 3/2/12


We can find out the class size by subtracting lower limit and upper limit


Example : The class size for the interval 20  29 is 29 – 20 = 9
