  1. Estimating Extravaganza

  2. question • Who are better at estimating males or females?

  3. Purpose • 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.

  4. hypothesis • I hypothesize that females are the best estimators. I believe this because most of the girls I know have an A in math.

  5. procedure

  6. Materials • 1. Markers • 2. Marbles • 3. Color pencils • 4. Cubes • 5. Snap cubes • 6. A see thorough bin

  7. variables • Manipulated: males or females • Responding: Estimates • Constant:Size of bin and the number of items

  8. directions • 1. Gather materials • 2. Fill a see though bin with snap cubes. • 3. Walkaround 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.

  9. 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.

  13. conclusion • 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.
