Data: $6, 9, 18, 27, x, 37, 41, 26$

What will be its mean deviation?

The mean and mean deviation of a set of $8$ observations is $19$ and $6.25$ respectively. It was later found out that one of the observations was wrongly read as $32$ instead of $40$. What is the difference between the correct mean deviation and incorrect mean deviation?

At the end of the year, Mahesh analysed his last five-month salary figures. He found the mean and median salary figures as $\mathrm{Rs}. 6 \mathrm{lacs}$ and the only mode salary figure as $\mathrm{Rs}. 8 \mathrm{lacs}$. If all his salaries are in lacs then what is the sum of the highest and the lowest salary earned by him?

If the mean of the first $7$ positive integral multiples of $13$ is denoted by $\mathrm{p}$ and the median of the same numbers is denoted by $\mathrm{q}$, then what is the value of $\mathrm{p}-\mathrm{q}$?

Mean deviation about the median for the following data:

$4,6,9,3,10,13,2$

The mean deviation from the mean of the series $\left(a\right), (a+d), (a+2d),\dots \dots \dots ,(a+2nd)$ is

For calculating mean deviation, deviations cannot be taken from any average.

Calculation of mean deviation is based on observations unlike range or quartile deviation which considers only limits.

While measuring dispersion using mean deviation, the value is not affected as much by the extreme values.
