Six people participate in a coordination study. They are each timed (in seconds) for how long they can jump rope without a mistake with their eyes open. Then, they each repeat the task with their eyes closed. For each individual, the difference in times is calculated. The purpose of the study is to determine if the lack of vision in normally seeing individuals decreases (hint for Steps 2, 4, & 6) coordination.
