A researcher was interested in the emotional effects of music on exam performance. Before their exam, a professor took one group of students into a room in which calming music was played. A different group of students were taken to another room in which new wave hard rock was being played. The students then took the exam and their scores were reported. What type of analysis would be most appropriate?
A.Paired (dependent) t-test
B.Independent (unpaired) t-test
C.Analysis of Variance ANOVA
D.Repeated Measures ANOVA
B independent
B.Independent (unpaired) t-test
C. Analysis of Variance (ANOVA)
The most appropriate type of analysis in this scenario would be Analysis of Variance (ANOVA). ANOVA is used to compare the means of two or more groups to determine if there are significant differences among them. In this case, the researcher wants to compare the exam performance of students who were exposed to different types of music (calming music vs. hard rock). ANOVA would allow the researcher to determine if there are any significant differences in exam scores between the two groups of students.
The most appropriate type of analysis for this scenario would be D. Repeated Measures ANOVA.
In this study, the same group of students is exposed to two different conditions (calming music and hard rock) before taking the exam. Since the same group is exposed to both conditions, this is considered a within-subjects design or a repeated measures design.
Repeated Measures ANOVA is used when the same participants are measured under different conditions or at different time points. It allows for the analysis of differences between the conditions while also accounting for individual differences or variation within the participants.
This analysis would be appropriate to compare the effects of calming music and hard rock on exam performance within the same group of students. It would analyze whether there is a significant difference in exam scores between the two music conditions and provide insights into the emotional effects of music on exam performance.
