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

Setup: Today we are going to take our data sets -- divided into QUARTERS -- and use them to make a box plot

Start with this data: 17, 18, 19, 20, 21, 23, 23, 26, 28 (Minutes spent doing chores) and divide it into four equal groups

Make a number line (skip count)

Think out loud while marking the dots above min, max and Q1, Q2, Q3. Draw the whiskers and make the box

Turn and talk: what did I do first, second, third?

For each of the following data sets, make a box-plot.

2, 7, 7, 7, 8, 9, 13, 14, 18

3, 5, 6, 8, 9, 10, 10, 13, 14, 19

2, 3, 4, 7, 9, 11, 11, 11, 18

A box plot, or box and whisker plot, is a graphical tool that displays the distribution of a dataset using 5 numbers: the minimum, maximum, Q1, Q2, and Q3

Steps for making a box plot:

1. Order the data from least to greatest and divide the ordered data into 4 equal parts (number ninja)

2. Create a number line (with correct spacing) that starts with the min and ends with the max

3. Make dots above the number line that represent the min, max, Q1, Q2, and Q3.

4. Make a box around Q1, Q2, and Q3. Draw whiskers to the min and max.

1. In your notebook, make meaningful notes for your forgetful selves

2. CYUQs → For each of the following data sets, make a box-plot. Do in your notebook. You chose where you want to start. Check answers as you’re working. If you need help, get help. And if someone else needs help, give help.

16, 20, 21, 22, 22, 24, 24, 26, 27

5, 6, 7, 8, 9, 11, 12, 12, 15

18, 19, 20, 20, 21, 23, 24, 27

45, 42, 50, 44, 47, 42, 53, 49, 46, 54

35, 44, 38, 32, 46, 41, 35, 48, 40, 37
