SWBAT… use and draw charts Thurs, 5/10
Agenda 1. WU (20 min)2. Box and whisker chart (25 min)
Warm-Up:1. Work on HW#1 and HW#2 for 20 minutes –
compare charts with each other

Box and Whisker Plot A box and whisker plot is a method of representing
data It helps people see where most of the data falls
WhiskersWhiskers BOXES

Box and Whisker Plot It shows a picture of data divided into four parts The boxes represent 50% of the data while each
whisker represents 25% of the data. The total represented by the entire plot is 100%
25%25% 50%

Drawing a Box and Whisker Plot
You must first find 5 things:
1. Lower Extreme
2. Upper Extreme
3. Lower Quartile
4. Median (Quartile 2)5. Upper Quartile
(median of 1st half)
(median of 2nd half)
![Page 5: SWBAT… use and draw charts Thurs, 5/10 Agenda 1. WU (20 min) 2. Box and whisker chart (25 min) Warm-Up: 1. Work on HW#1 and HW#2 for 20 minutes – compare.](https://reader036.fdocuments.in/reader036/viewer/2022062422/56649ec85503460f94bd53f7/html5/thumbnails/5.jpg)
Example 1
Draw a box and whisker plot for this data:
4, 7, 15, 27, 9, 14, 12, 22, 9, 11, 18
First, we must put these numbers in order from least to greatest.

Example 1
Draw a box and whisker plot for this data:
4, 7, 9, 9, 11, 12, 14, 15, 18, 22, 27
Now we can find those 5 things that we need.

4.4. Median (Quartile 2) --- Median (Quartile 2) --- 1212
5.5. Upper Quartile --- Upper Quartile --- 1818
Now we can draw a box and whisker plot for this data.
