A project on free throw percentage

Henry Weiner Science Fair Project

Problem• What effect does gender have on free

throw percentage with a 28.5 size ball?

Henry Weiner Science Fair Project

Hypothesis

• I predict that the boys will shoot a little better than girls, because the free throw percentage in professional and college basketball is higher in men than in women.

Materials

• 5 seventh grade boy basketball players• 5 seventh grade girl basketball players• 28.5 basketball• Basketball court• Basketball goal• Spreadsheet (to record results)• Pencil• Clipboard

Procedure

1. Gather all materials2. Get an open gym3. Gather test subjects4. Have them shoot ten free throws

and two warm up free throws5. Record their results6. Calculate their percentage7. Average the boy’s average, and the

girls’ average separately

Observations

• I noticed that some of the test subjects, both boys and girls, got mad at themselves, and stopped to shoot as well.

• Some of the people had not shot a basketball in quite a while, and missed quite a few of their shots.

Conclusion

• My hypothesis was correct. The boys shot an average of 50%, but the girls only shot 30%. Boys do indeed shoot free throws better than girls.
