The data set represents the number of times six students checked their phone in an hour:

6, 5, 9, 2, 0, 8

Find the Mean Absolute Deviation (M.A.D.)

The Mean Absolute Deviation (MAD) helps us to see how spread out the data is (relative to the mean).

Data that are similar to each other will have a smaller number (spread), whereas data that are more different from each other will have a larger number (spread).

When would you use this in real-life?

Within statistics, there are two large categories:

Measures of Central Tendency

Measures of Variability

Let's review, compare and contrast, and glue the graphic organizer into our notebooks.

Write down at least three things to remember about this topic in your math notebook (include examples)

1. Check-your-understanding questions (CYUQs): Do your own, you choose where to start, check your work with the students around you. If you need help, get help. If someone needs help, give help.

* Be sure to choose at least 3 from each of the three types of problem sets (for a total of 9 practice problems)
