Problem Set 4: One way repeated measures ANOVA

Research Scenario: A savvy business owner wanted to assess whether type of background music influenced the amount of money spent. For four Saturdays, he varied the type of background music being played: pop, rock, classical, and country. Amount of money spent (in hundreds) is reported for each type of music. Conduct a one-way repeated measures ANOVA to determine whether background music influenced total amount of money spent.

14) Paste the relevant SPSS output.

15) Create an appropriate graph to display this data (make sure you have labels on both x and y axes).

16) Write an APA-style Results section based on your analysis. All homework “Results sections” should follow the examples provided in the presentations and textbooks. They should include the statistical statement within a complete sentence that mentions the type of test conducted, whether the test was significant, and if relevant, effect size and/or post hoc analyses. Don’t forget to include a decision about the null hypothesis.

First you should enter the data in SPSS as

14) The relevant output is

15) The appropriate graph to display the data is

from the above boxplot ,each area of the boxplot is overlapp with each other .Hence ,the money from different types of music may be insignificant .

16) The estimated p-value of music factor is o.126 and more than 0.05 level of significance.hence ,we can conclude that money amount spends on each of the music is the insignificant difference at 0.05 level of significance
