  1. The Estimates

  2. Question Today mygroup decided to answer this question for the science fair: Who is better at estimating the unknown male or females?

  3. Purpose The purpose of this project is to determine who is better at estimating the unknown, males or females. This is important because we want to see if boy or girl thinking is better. We would know who to go to if we needed an estimate.

  4. Hypothesis Our hypothesis is that the girls will be better estimators then males. We believe this because in our class girls get better grades in math class.

  5. Procedure

  6. Materials • Skittles • Snap cubes • Gram cubes • Marbles • Pencils • Jar

  7. Variables Manipulated variable: male or female Responding: estimate estimates Constant- objects in jar for each trial -number of male and female estimators -size of jar

  8. Directions Count the candy. Write the number down. Keep number hidden Place candy in the jar. Have estimators estimate the same number of candy in the jar. Record estimates. Repeat steps 1-3 with snap cubes Repeat steps 1-3 with marble Repeat steps 1-3 with pencils Calculate the average estimates Calculate the average difference between actual and average estimates.

  9. Average Difference Between Actual and Estimates

  10. CONCLUSION • Our hypothesis was incorrect. Males are better than females. The average difference between the actual and the estimate for males was 75.62. The average difference between the actual and the estimate for females was 75.94. We repeated this investigation again we would ask more people to estimate.
