Question

Find the median of the following series :
`{:("Size",2,3,4,5,6,7,8,9,10),("Frequency",2,3,8,10,12,16,10,8,6):}`

Answer 1

Median of = Size of `((N+1)/(2))` th item
= Size of `((75+1)/(2))`
Size of 38 th item
It shown that median value corresponds to the 38th item in the series . This item appears first of all in 51 1 st cumulative frequency of the sercies . Therefore, median shall be the value corresponding to the 51 st cumulative frequency , which is 7.
Median =7
