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.

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)

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