[00:00:00]is on mean deviation. So, let's say that you will take the test in a subject and score 70, 80 and 90. On an average, your score is 80 but this is a thing. Not every score is exactly 80, right? So mean deviation is how much it is fluctuating from the average value.

[00:00:14]Step one, first you have to find the mean.

[00:00:16]Step two is how much it is deviating from that.

[00:00:18]Meaning +10, -10 these three. So total deviation 10, 0 and 10. So here we will not take negative values.

[00:00:25]Deviation means it will be taken as positive. So the total deviation becomes 20 / 3 6.67, so my mean deviation becomes 6.67.

[00:00:34]Any data is very useful and sometimes in terms of cricket, I am choosing only that player who performs on a regular basis. So mean deviation equals average distance from the mean.
