Find the mean, median, and mode of 13, 30, 16, 19, 20, 22, 25, 31.

I think 19.5 is the median

Step-by-step explanation:

Here's a song my fifth grade teacher taught us to help remember what each term means:

"Mode mode mode is the most. average is the mean, median median median is the number in between."

Mode: The mode is any number(s) that are repeated. In this case, there are none.

Median: Arrange the numbers from least to greatest and cross them out from the outside as you go. Sometimes you're left with just one answer, but in this case we're left with 20 and 22.  You would add 20+22 and divide by 2... so the answer is 21.

Mean: To find the mean, you add up all of the numbers and divide by the amount of numbers there are (in this example there are 8). The mean is 151.
