AMAZING ESTIMATERS. WHO IS BETTER AT ESTIMATING MALES OR FEMALE S?. Purpose. The purpose of this project is to determine if boys or girls are better at estimating. This is important because if you want a good estimate you will know whether to ask a boy or a girl. Hypothesis.

Purpose

The purpose of this project is to determine if boys or girls are better at estimating. This is important because if you want a good estimate you will know whether to ask a boy or a girl.

Hypothesis

• We hypothesize that girls are better at estimating. We think this because last year at the Spring Fling, of the three estimating contests, two were won by girls.

MATERIALS

• One bag of M&M’s

• Five pieces of paper

• Two boxes of Reese Pieces

• Marbles

• Jar

• Pencils

Variables

• Manipulated/Independent: Male of Female

• Responding/Dependent: Average estimate

• Constant: Amount of objects in the jar for each trial and the size of the jar

DIRECTIONS

1. Count and record the number of M&M. Keep count hidden from test estimators.

2. Place M&M in a clear jar.

3. Have estimators estimate the number of M&M record estimate.

4. Repeat steps 1-3 with marbles.

5. Repeat steps 1-3 with brads.

6. Repeat steps 1-3 with pencils.

7. Repeat steps 1-3 with Reese Pieces.

8. Calculate the average estimates.

9. Calculate the average difference between actual and average estimates.

CONCLUSION

Our hypothesis was incorrect. Males are better at estimating. The females average difference was 107.08. The males average difference was 119.23. The thing we could change if we did this investigation again is the materials and the using same amount of females and males. We would also estimate height and distance instead of just objects.
