9.2-9.3: Mean, Median, & Mode

Mean, median, & mode example (video) | Khan AcademyHere 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!

9.4 Interquartile Range

9.4 Interquartile Range Example!

Interquartile range (IQR) (video) | Khan AcademyThe 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 data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

9.5 Mean Absolute Deviation (MAD)

Mean absolute deviation (MAD) (video) | Khan AcademyMean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.
