Q. 5

# Find the mean dev

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 = 50

SO, The cumulative frequency just greater than 25 is 58, and the corresponding value of x is 28

Median = 28

Now, Mean =

Mean = 27

Mean deviation from Median

And, Mean deviation from Median

Hence, The Mean Deviation from the median is 9.56 and from mean is 9.44.
