Use the frequency data to fill in the blank cells in Table 1 below. (Hint: You can obtain this data using either Descriptive Statistics  Crosstabs… or using the Split File function and Descriptive Statistics  Frequencies…)

QUESTION 14

QUESTION 15

Interpret and report the results of the t-test output provided for Question 14. Do there appear to be sex differences in IQ for the sample of children included in your study?

Finally, provide at least one sentence interpreting the findings (i.e., do the findings provide support for the proposed Mozart Effect?)

QUESTION 18

Use SPSS Chart Builder to create a Simple Bar Chart showing the mean differences in children’s IQ across the three music conditions included in the study. Be sure to include error bars on the figure depicting the standard error of the mean. After producing the bar chart figure, use the SPSS chart editor to edit the figure. Copy and paste the final figure below and include an APA-style title.
