To find median . . . list the number in order from least to greatest
10 , 11, 12, 12 13, 15
Then cross of a number from each side until you get to the middle number or middle 2 numbers.
IF there are 2 numbers add them together and divide by 2
12 + 12 = 24
24 / 2 = 12
Your median is 12
To find mean (this is the same as average) add all the numbers to get a total.
10 + 11 + 12 + 12 + 13 + 15 = 73
Then count the number of items added . . .6
Take the total and divide by the items counted
73 / 6 = 12.1666
Your directions say to round to the nearest tenth place.
12.166 = 12.2

9 ___ 15 ____ 20 ________5___ 25
10 __ 21 _____19 ________ 2 ___ 4
Mean squared error :
(4 + 4 + 0 + 9 + 25 + 4) / 6
= 46 / 6
= 7.666
= 7.67
