Box-And-Whisker Plots By Virginia Vimpeny Lewis

What information do we need? Minimum data value Lower Quartile Median Upper Quartile Maximum data value Outlier values

What does it Look Like?

What are the parts? Minimum Value Lower Quartile Median Upper Quartile Maximum Value

What if there are outliers? 2 nd lowest value Lower Quartile Median Upper Quartile 3 rd highest value Outlier

How to Identify the Range? Minimum Value Maximum Value Range The range is the distance between the Maximum and Minimum Values

How to Identify the Interquartile Range? Interquartile Range The interquartile range is the distance between the Upper and Lower Quartiles. Lower Quartile Upper Quartile

How is the data divided? There are four sections of a box-and-whisker plot. Each section contains one-fourth or 25% of the data. 25%
