I. Averaging

In an experiment, Frank measured the area of different types of leaves. Here is his data.

  1. Find the median area for each type of leaf.
  2. Graph the median area for each type of leaf on Centimeter Graph Paper.
    • Put Type of Leaf (T) on the horizontal axis.
    • Put Area (A) on the vertical axis.
    • Scale the vertical axis by fives.
    • Title and label the graph.
