Why does the ghost come back to the
library every day for more books?
Answer: Because it goes through them too
quickly.
Out of 150 surveys sent out, we only had 60 survey returned with fully filled out information. 24 out of 150 surveys were never returned and the remaining 66 either hadn’t taken the test yet or didn’t state how many books they read. From this, we can say that there is a non-response bias. Some of the people in the 24 students that didn’t return the survey may have gotten a lower score, so they may not want to make their scores made public. Since people with higher scores will be more inclined to be truthful, this response bias could have negatively skewed our data.
Another weakness may have been the wording of the survey. When we asked whether they took ACT or SAT, we gave them choices, SAT, ACT or both; there was no neither option. People may have felt compelled to arbitrarily make some thing up so as not to leave the survey blank. These made up scores would have certainly affected our results.

Suggestions
Other studies could be conducted based on this topic. One of the confound variables was that people may have lied about their test scores. In order to prevent this in the future, a study could be conducted where the test scores are directly accessed by the researcher. Another study to do would be to survey a broader population which includes the nearby schools. This would allow the results to be extrapolated further.
