Eye Dominance In Basketball
Crossed Up: Does Crossed Hand/Eye Dominance Affect Basketball Shooting Percentage?
Abstract
Everyone 's used to the idea that people are either right-handed or left-handed for particular tasks. That is, one hand is preferred (or dominant) over the other for a particular task. Did you know that people also have a dominant eye? This project is designed to look for consequences of having the dominant hand and eye on the same side of the body (uncrossed) vs. having the dominant hand and eye on opposite sides of the body (crossed).
Objective
The goal of this project is to determine whether crossed hand/eye dominance helps or hurts when shooting basketball free throws.

Materials and Equipment
To do this experiment you will need the following materials and equipment:
50–100 volunteers to take hand and eye dominance tests and then shoot free throws; …show more content…
The trick is that you will need to be able to test (or survey) each player to find out their dominant hand and dominant eye. As in the experiment described above, it would be best to have at least 50–100 participants in your study, so you 'll need to test (or survey) a lot of players. Each player you include in your study will also need to have a significant number of freethrow attempts over the course of the season, so that you know the freethrow shooting percentage is reliable.
What do you think the effect of crossed hand/eye dominance would be in other sports, e.g.: hitting a baseball, archery, target rifle shooting, soccer, or golf? Design an experiment to test your hypothesis.
Experimental Procedure
1. Do your background research so that you are knowledgeable about the terms, concepts, and questions, above.
2. You 'll need to recruit 50–100 volunteers for this project. Ideally all of your volunteers will be approximately the same age, and will have roughly the same amount of experience shooting free throws.
3. The simplest way to collect the data for this experiment is to use a separate data sheet for each participant. On each data sheet you will need to collect the following information:
a. Name
b. Age
c. Gender
d. Hand dominance
e. Eye
