No.of Families  10 14  15  21  28  7  5  

n = 100

Median =L+  

G

(n/2)−B

​  

×W

Median =252+

(50−39)

​  

×175

Median =616.667

Where L = Lowers limit of median class

B = C.F of class before median class

G = Frequency of median class  

W = class width

Mode L+=  

(fm−fm−1)+(fm−fm+1)

fm−fm−1

​  

×W

Mode =700+  

21+7
