Descriptive Statistic Calculations
For the following questions, consider this data set:
I wonder if racial stereotypes would actually effect athletic performance? What if we asked people of different races to complete a miniature golf course after activating some commonly held racial stereotypes? This study led participants to believe that the golf was either testing their natural ability or testing their IQ. Would the racial stereotypes about IQ and athletic ability effect performance?
40 African-American and Caucasian undergraduates at Princeton University (so they are all really smart!) were recruited to participate in a study on sports psychology. No one with extensive knowledge of golf (e.g., members of the golf team or students who reportedly played more than once a week) was used in the study.
The participants were randomly assigned to either the 'Natural Ability' condition or the 'Sports IQ' condition. Participants in the natural athletic ability condition read that the test was designed to measure personal factors correlated with natural athletic ability. Natural athletic ability was defined as "one's natural ability to perform complex tasks that require hand—eye coordination." Participants randomly assigned to the sports intelligence condition read that the test was designed to measure "personal factors correlated with the ability to think strategically during an athletic performance."
Participants were then asked to complete the miniature golf course with the goal of completing the course with the fewest possible strokes. Larger numbers of strokes indicate worse performance.
Here is that data:
