What is a mean? Attach a video explaining mean.

Average, which is the sum of values divided by the number of values

Step-by-step explanation:

A mean is another word for average.

Example:

Say you have a group of numbers, a data set it you will.

3 4 5 7 8 9 6 4 2 8 9

1. Add them all up: 3+4+5+7+8+9+6+4+2+8+9 = 65

2. Divide: (total sum of all numbers) ÷ (amount of numbers in set) -- 65 ÷ 11 = 5.909

3. Round to the specified or given amount. (Generally, this is either to the next whole number or the nearest tenth.)

4. Average ≈ 6 (to the next whole number) or Average ≈ 5.9 (nearest tenth)
