ESTIMATING EXTRAVAGANZA

Who are better at estimating males or

females?

QUESTION

The purpose of my investigation is to

determine who is better at estimating males or

females. This is important because if we ever had a project I would know who to chose as a partner.

PURPOSE

I hypothesize that females are the best

estimators. I believe this because most of the girls I know have an A in math.

HYPOTHESIS

PROCEDURE

1. Markers2. Marbles

3. Color pencils4. Cubes

5. Snap cubes6. A see thorough bin

MATERIALS

Manipulated: males or females

Responding: Estimates

Constant: Size of bin and the number of items

VARIABLES

1. Gather materials2. Fill a see though bin with snap cubes.3. Walk around classroom with bin. Ask 10 girls and 10 boys to estimate the number of snap cubes in the bin. Record.4. Empty bin and count the number of cubes. Record.

DIRECTIONS

5. Calculate the difference between the actual count and estimate. Record.6. Repeat steps 2-5 with markers.7. Repeat steps 2-5 with cap erasers.8. Repeat steps 2-5 with colored pencils.9. Repeat steps 2-5 with marbles.

My hypothesize was correct. Females are better estimators then males. The

average between the actual number and the estimates for females was 49.96 and males was 69.22. Now that I did males

and females with objects in a bin, I what to see if they could estimate height and

if females will be better at that too.
