Nice job on the last test! The scores are in PowerSchool.

Your job: write down ten (10) things that have to do with math.

Your job: write down ten (10) things that have to do with math.

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.

p815 10, 11, 12, 13; p813: 1, 2, 3, 4; p812: 1, 2 (Volume 2, Chapter 11, Lesson 1)

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

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.

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.

What is a box-plot?

Min: smallest number in the data set

Max: largest number in the data set

Q1: the median of the lower half of a data set

Q2: median or middle of the entire data set

Q3: the median of the upper half of the data set

* To identify each part of the Five-Number Summary, the data set must be ORDERED least to greatest

Steps for finding Min, Max, Q1, Median (Q2), and Q3:

1. ORDER the data from least to greatest

2. Circle the median

3. Draw a triangle around the median in the LOWER half of the data set

4. Draw a rectangle around the median in the UPPER half of the data set

5. Label each of the five items in the Five-Number Summary

If the data set has an even number of values, the median is the average of the middle 2 values in the data set.

If the data set has an odd number of values, DO NOT include the median when finding the first and third quartiles.

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.

Do at least three of the problems with an EVEN number of items in the data set:

Do at least three of the problems with an ODD number of items in the data set:

Do at least two problems with 10 - 16 items in the data set:

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

Quartiles: values that divide the data set into four equal parts.

Each quartile represents 25% of the data.

Interquartile Range (IQR): the distance between Q1 and Q3
