THE UPSIDE DOWN HAIR GRAPH

Data Management

Purpose: To make a graph representing hair length of people in the classroom.

Skill: Graphing, comparisons

Directions:

1. Collect one hair from the head of a friend. Cut a piece of yarn equal to the length of the hair. Tape it to a line (as shown) and label it with the name of the individual.

2. Repeat this process until you have about 10 pieces of labeled yarn.

3. What do you notice about the chart?

How does it compare to an upside down bar graph?

Can you think of a way to find the average length of hair?

Can you make any generalizations about the length of boys' hair as compared to the length of girls' hair from your graph?
