Question

What is the mean for the data set?
8 10 6 4
12 6 8 14

Answer 1

`8(1)/(2)`

Explanation:

First add up all the numbers:

8+10+6+4+12+6+8+14=68

Now you have to divide the sum by the amount of numbers. There are 8 numbers.

`(68)/(8)=(34)/(4)=(17)/(2)`

`(17)/(2)=8(1)/(2)`

Answer 2

8.5

Explanation:

To find mean, we simply take the average of all the numbers in the data set, and divide in by the amount of values!

`8+10+6+4+12+6+8+14= 68\\`

68 ÷ 8 = 8.5!
