Question

Sarabeth used a box-and-whisker plot to summarize her race times in minutes. She didn't include her latest race time of 28 minutes. How will the inclusion of this new time affect the box-and-whisker plot?

Answer 1

Depending on if this makes an outlier, or if it is not. If it is then it will change the mean a good bit positive or negative depending on if it is it being a high or low outlier. The median will not be as effected by this new number because it will only move one point in either direction.
