Calculate the mean, median, or mode of a data set!

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).

Here we give you a set of numbers and then ask you to find the mean, median, and mode. It's your first opportunity to practice with us!

The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the …
