After completing the Check-your-understanding Questions, which were important for everyone to do?

Pick one or two problems that you did and show your work to you seat partner.

1. I asked 8 students how many pets they have at home. This is the data: 4, 2, 3, 1, 3, 0, 4, 3 What is the mean?

2. Find the absolute value for the following:

a. |-38|

b. |16 - 7|

* Reminder: absolute value is the distance a number is from 0

The Mean Absolute Deviation is the average distance between each data value and the mean.

To find the MAD:

1. Find the mean of the data set.

2. Find the absolute value of the difference of the mean and each data point |data point - mean|

3. Find the mean of the absolute values you found in Step Two.

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.

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

3. Don't give up! If you get stuck, choose to persevere: review your thinking, try another approach, ask for help, search
