Dr. Doodley hypothesized that fast music would enhance people’s work performance. To test her hypothesis, she chose two different secretarial pools and chose to control what speed of music they would be working with, making that the independent variable, while the dependent variable is the performance of the groups based on the type of music they listened to while working. Based on the experiment’s purpose, the experimental group is the pool exposed to fast music. In which case, the control group would be the pool exposed to slow music. The control group used for the experiment was not appropriate, because there was a malfunction with the tape. There are several things wrong with Dr. Doodley’s experiment, such as the fact that she forgot to include a group with no music, for reference. Another problem that could have affected the experiment’s outcome was the hiss that resulted from the old tape, thus possibly making it difficult for the slow-music pool to perform well. Dr. Doodley may have also failed to consider if the slow-music group’s work required critical thinking, so if any music at all could have decreased the quality of work. This would give a false advantage to the fast-music group. Which is why I …show more content…
Doodley should consider is fixing the hiss from the tape, which might not only change the results of the performances, but also help make the slow-music pool a better control group. I believe it would also help to increase the length of the experiment and the number of people sampled. Lengthening the time period of the experiment would lessen people’s focus on the experiment and instead enable them to work as they usually would. It’s also plausible that there were more people in the slow-music group who required more time to adjust to working with music, as well as the hiss. As for the performance evaluations, the results may have been more accurate had the supervisors evaluated the employees
