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
