How do you identify outliers in a box and whisker plot?

Back

Outliers are typically identified as data points that fall below Q1 - 1.5 * IQR or above Q3 + 1.5 * IQR.

Front

What does it mean if a box and whisker plot is skewed to the right?

Back

If a box and whisker plot is skewed to the right, it indicates that there are a few high values that are pulling the median and the box towards the higher end.

Front

What percentage of data falls between Q1 and Q3?
