Data Presentation

Data is only as good as how it is presented. How do you take hundreds or thousands of data points and create something a human can understand? Check out the world of charts, graphs, and more.

Box Plots

         

Which of the following is closest to the largest value in the data set represented by the box plot above?

Consider the box plot above which was generated from a set of 9 values. If the largest possible mean of the numbers (i.e. their arithmetic average) is \(m\), which is closest to \(9m\)?

Hint: think of what values the box plot tells us must be in the data set.

The box plot above represents a series of measurements. Which is closest to the largest measurement?

What is the mean of the numbers in the data set represented by the box plot above (note: the mean of some numbers is the arithmetic average of them).
