1. Warm Up Find the 5# Summary and IQR of the following data sets. 1.{37, 44, 5, 8, 20, 11, 14} 2.{10, 1, 3, 4, 30, 4, 20, 22, 10, 25}

2. EQ: What is a Box Plot? Agenda: Notes on Box Plots Group Work In-Class NBA activity Homework assignment

3. Box Plots A box plot is a graphical display of the 5# Summary. Box plots are good at summarizing large amounts of data. A box plot is sometimes referred to as a Box-And-Whisker Plot.

4. Box Plots A box plot displays the range and distribution of the 5# summary’s data along a number line. This number line MUST be an interval scale. This means that the numbers on the scale are uniform.

5. Box Plot Scales For Instance, 010131930323436330510152025354030

6. How to draw a box plot A box plot is drawn from a 5# Summary. Begin by finding the 5# Summary and IQR of the following data set. 301210842 71016703 1231027915 514156

7. How to draw a box plot Then draw a scale to represent the data found. Range: ________ 0 1424 6 8 101612 18

8. How to draw a box plot Draw short, vertical lines above Q 1, M, and Q 3. Form the “box.”

9. How to draw a box plot Put a dot above the lowest and highest data point. Draw the “whiskers” from these points to the box.

10. Example #2 Find the 5# Summary, the IQR and draw a boxplot of the following data set. 0001133 55788914 25252629424452 729298118

11. Steps Find 5# and IQR Determine and Draw Scale Vertical Lines above Q 1, M, and Q 3 Draw Box Mathematically Identify any Outliers!!!

12. How to Find Outliers Any data point that is more than 1.5 times the IQR above Q 3, or below Q 1 is considered an outlier. On the scale put a single dot above any outlier.

13. Summary Find 5# and IQR Determine and Draw Scale Vertical Lines above Q 1, M, and Q 3 Draw Box Determine and Mark Outliers Draw Whiskers

14. Describing a Box Plot The distance between the points in the box plot tells you about the distribution of the data in the quartiles. A shorter distance means: A longer distance means:

15. Box Plots of the Warm Up Go back to your Warm Up. Find the 5#, IQR, Determine outliers, and draw a Box Plot. Describe the distribution of data points in the quartiles.
