# Calculate mean de

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 = 20 So, the cumulative frequency just greater than 10 is 12, and the corresponding value of x is 15

Median = 15

Now, Mean =  Mean = 14.1 Mean deviation from Median And, Mean deviation from Median Hence, The Mean Deviation from the median is 6.9 and from mean is 6.99.
