THE ESTIMATORS

QUESTIONToday my group decided to answer this

question for the Science Fair: Who is better at estimating the unknown, males or females?

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 BOYS OR GIRLS THINKING IS BETTER SO WE WOULD KNOW WHO TO GO TO IF WE NEEDED AN ESTAMATE.

HypothesisWe hypothesize that girl will be better

estimators than females. we believe this because in our class girl get better grades in math class.

VARIABLES

MANIPULATED: males or females

RESPONDING: estimates

CONSTANT: Objects in jar for each trialNumber of male and female estimaters Size of jar

Directions 1 Count the candy. Write the number hidden. 2 Place candy in the jar.3 Have estimators estimate the same number of

candy in the jar. Record estimates. 4 Repeat steps 1-3 with snap cubes. 5 Repeat steps 1-3 with gram cubes.6 Repeat steps 1-3 with marble. 7 Repeat steps 1-3 with pencils. 8 Calculate the average estimates. 9 Calculate the average difference between

actual and average estimates.

FEMALES

CONCLUSIONOur hypothesis was incorrect. Males are

better estimators 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.
