Question

Find the median of the following frequency distribution : 

Weight(kg)	36	38	40	42	44
No. of students	11	26	29	24	10

Answer 1

Weight (kg)	No. of students  (f)	Cumulative frequency
36	11	11
38	26	37
40	29	66
42	24	90
44	10	100

No. of terms = 100 
The mean of 50^th and 51^st term is the median 
50^th and 51^st terms lay under 40 and 40 

median = `(40+40 )/2 = 40`

Hence, Median = 40
