        The Lesson

        Part I: Learning Activity

        1. Read the following to your students: "Harry can't stop sneezing. His doctor asks him to keep a record of where he sneezes as well as the number of times he sneezes. He thinks Harry may be allergic to something."

        2. Tell the students to watch to see how Harry figures out what is causing him to sneeze.

        3. Play the  Harry's Allergy QuickTime Video .

        4. Tell the students that the information collected by Harry can be used to create a graph called a Histogram.

        5. Distribute Handout 1: "Displaying Survey Information as Graphs" .

        6. Discuss the handout with students. Focus on the way a survey is conducted, the ways in which you can construct a histogram, and in the case of allergies, the statistic that is used to describe the most common cause of allergies. This is called the mode.

        Part II: Assessment

        Assessment: Level A (proficiency): Students make a histogram from a data table. 

        Assessment: Level B (above proficiency): Students draw conclusions using data from two histograms.
