This is a review for finding the median value of three trials in an experiment.

Cheap-O 37 sq cm

K. Finding Medians

Here is Jackie's data for a paper towel experiment. She dropped water on one sheet each of three different brands of paper towels (Ecotowel, Cheap-O, and Handy). She dropped three drops of water on each towel. The water spread out and made a spot. Jackie then measured the area of each spot of water in square centimeters.

Find the median area for each type of towel and write it in the table.
