Audrey surveyed 10 stores in a shopping mall about how many employees they have. She created a box-and-whisker plot to display her data. Which statement describes whether a line plot of Audrey's data can be created using only her box-and-whisker plot?

• A line plot of Audrey's data cannot be created because a box-and-whisker plot does not display the mean of the data set.

• A line plot of Audrey's data cannot be created because a box-and-whisker plot does not display each individual data point.

• A line plot of Audrey's data can be created because a box-and-whisker plot shows each individual data point as a vertical line segment.

• A line plot of Audrey's data can be created because knowing the minimum, maximum, and each quartile is enough information to find the individual data points.

Answer explanation

You need each individual data point to make a line plot and box-and-whisker plots only give you the minimum, maximum and each quartile.
