Calculate the mean deviation about median age for the age distribution of 100 persons given below:Age      16-20     21-25    26-30     31-35    36-40      41-45    46-50    51-55Number   5             6           12         14          26          12          16         9

Explanation

To calculate the mean deviation about the median age for the given age distribution of 100 persons, we will follow these steps:

### Step 1: Convert Age Groups to Continuous Intervals
The age groups provided are not continuous, so we will convert them to continuous intervals by adjusting the lower and upper limits.

- For 16-20, the continuous interval is 15.5 to 20.5
- For 21-25, the continuous interval is 20.5 to 25.5
- For 26-30, the continuous interval is 25.5 to 30.5
