Can someone explain how to find mean and absolute deviation

A mean is an average number so you’ll need to add all the numbers and dived it by the numbers there are. For example,

2,4,6,9.

You’ll need to add all the numbers which is 21. Then count the numbers. There are four numbers, so you’ll divide, 21 ÷ 4 = 5.25 , and that how you find the mean.

Now for absolute value, it will be the number distance from 0. For example,

the numbers 5. The absolute value will be -5.
