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.
CONCLUSION
