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.★
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.
Draw a box-and-whisker plot on a number line.
Ex. 1 16, 12, 14, 19, 19, 7, 4, 19
Draw a box-and-whisker plot on a number line.
Ex. 2 20, 4, 19, 16, 2, 2, 8, 20, 20
Draw a box-and-whisker plot on a number line.
Ex. 3 17, 1, 15, 13, 6, 4, 9, 3, 13, 2
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.
