Question

1. You want to construct a box-and-whisker plot from a data set. What is the first thing you should do?

Answer 1

Order the data values from least to greatest.

You need to order the data to get your median (fiftieth percentile)
and your lower quartile, and your upper quartile.

I was tempted to say

Find the range of the data set, but you need them in order to
see the lowest value and the highest value that are used to
display the range.
