The Plant Project

Answer the questions based on your line plot.

  1. What was the shortest plant height?

  2. What was the tallest plant height?

  3. What is the difference between the height of the tallest plant and the shortest plant? Write an equation to show how you know.

Problem 2

Answer the questions based on Han’s line plot.

 Line plot titled Plant Height from 22 to 32 by ones. Horizontal axis labeled length, in centimeters. Beginning at 22, the number of x’s above each increment is 1, 1, 1, 1, 1, 2, 4, 5, 2, 1, 1.

  1. Han looked at this line plot and said that the tallest plant was 29 centimeters. Do you agree with him? Why or why not?

  2. How many plants were measured in all?
