Boys vs. Girls

Question

Who are better estimators, males or females?

PURPOSEThe purpose of this project is to

determine who is better at estimating the unknown, males or females. This is important because when you need help you want to go to the person who is better.

HypothesisWe hypothesize that

females will be better at estimating. We believe this because they are good at math and school.

Procedure

Materials1. Jar2. Kit Kats3. Crayons4. Paper Clips5. Bracelets6. Rubber Bands

Variables

Manipulated: males and females

Responding: estimates

Constant: jar and the same amount of things in the jar for each trial

1. Put Kit Kats in the jar.2. Record how many kit Kats

in the jar.3. Ask males and females estimate the number of Kit Kats they think are in the jar.4. Repeat steps 1-3 with rubber bands. 5. Repeat 1-3 with paper clips. 6. Repeat 1-3 with pencils.

Directions

Directions7. Repeat 1-3 with crayons.8. For each trial, calculate the average estimate.9. For each trial, calculate the average difference between actual and average estimate.

Average Difference Between Actual And Estimates

ConclusionOur hypotheses was incorrect. Males are better at estimating. The average difference between the actual and the estimate for males was 93.24. The average difference between the actual and the estimate for the females was 129.94. It would be interesting to see if males were better at estimating other things such as height and distance.
