2. Box-And-Whisker Plots EQ: How do I draw a picture of data? MCC9-12.S.ID.2 Use statistics appropriate to the shape of the data 
distribution to compare center (median, mean) and spread 
(interquartile range, standard deviation) of two or more different data 
sets.★

3. 5-number summary: 1) Minimum - beginning of whisker 2) Lower Quartile - left side of box 3) Median - middle of box 4) Upper Quartile - right side of box 5) Maximum - end of whisker Together, we use these values to draw a box-
and-whisker plot.

4. Draw a box-and-whisker plot on a number line. Ex. 1 16, 12, 14, 19, 19, 7, 4, 19

5. Draw a box-and-whisker plot on a number line. Ex. 2   20, 4, 19, 16, 2, 2, 8, 20, 20

6. Draw a box-and-whisker plot on a number line. Ex. 3 17, 1, 15, 13, 6, 4, 9, 3, 13, 2

7. Outlier - a point that is more than 1.5IQR 
outside of the quartiles. In a box-and-whisker 
plot, we do not include outliers in the whiskers. Ex. 4 Draw a box-and-whisker plot  5, 7, 3, 4, 6, 5, 17, 2, 4
