3. Researchers at the University of California, Irvine, wished to determine whether music cognition and cognition pertaining to abstract operations such as mathematical or spatial reasoning "were related To test the research question, 36 college students listened to Mozart's sonata for two piano in D major, K488, for 10 minutes and then were administered the test. The 36 students also had to take the test after sitting in a room for 10 minutes in complete silence. The mean score on the test following the Mozart piece was 119, while the mean test score following the silence was 110. The researchers concluded that subjects performed better on abstract/spatial reasoning tests after listening to Mozart s this a completely randomized experiment, a matched pairs experiment, or an observational study? test after Mozart or taking the test after silence. Why was this done? student, the experimenters fipped a coin to determine which protocol came first taking the

Explanation / Answer

Result:

a).

This is matched pairs experiment. The same subjects are all be tested under each of the two treatment conditions.

b).

This was done for randomization.

This ensures that each participant or subject has an equal chance of being placed in any of the treatments. Thus, any differences recorded at the end of the experiment can be more confidently attributed to the experimental procedures or treatment.
