The age distribution of 100 life-insurance policy holders is as follows :

Calculate the mean deviation from the median age.

Given, Numbers of observations are given.

To Find: Calculate the Mean Deviation

Formula Used: Mean Deviation =

Explanation.

Here we have to calculate the mean deviation from the median. So,

N = 96

SO, The cumulative frequency just greater than 48 is 59, and the corresponding value of x is 38.25

Median = 38.25

Mean Deviation =

Mean deviation for given data

Hence, The Mean Deviation is 10.21.
