mean 20, median 15, mode, 22

mean 23, median 15, mode, 25

mean 16, median 19, mode, 22

Tranquility · Answer

To calculate the mean, add up all the numbers and divide by how many numbers there are. (There's 9 numbers.)
An example: 1, 4, 7, 8
Mean = (1+4+7+8)/4 
= 20/4 = 5

To find the median, arrange all the numbers in oder from least to greatest and find the middle number.
Ex. 1, 2, 3, 4, 5
3 is the median

To find the mode, you need to see which number occurs the most.
Ex. 1, 3, 6, 6, 6, 8, 9
5 is the mode because it appears the most times
