# Module 7 SPSS Data Interpretation

Directions:

Review the SPSS output file which reports the results of the between-group (independent group) factorial ANOVA to see if the mean alcohol by volume (%) differs as a function of rating given by beer expert (IV 1) and/or recommendation made by a beer connoisseur magazine (IV 2). Answer the following questions based on your observations of the SPSS output file:

1. Is the mean alcohol by volume level different for the type of rating given by the beer expert (main effect of IV1)? What are F-value and the significance level for this test (write result using the following notation:  F(df1, df2) = _____, p = _____).
2. Is the mean alcohol by volume level different for the type of recommendation given by the beer magazine? What are F-value and the significance level for this test (write result using following notation:  F(df1, df2) = _____, p = _____).
3. Is the mean alcohol by volume level different for different combinations of expert rating and magazine recommendation (interaction term)? What are F-value and the significance level for this test (write result using following notation:  F(df1, df2) = _____, p = _____).

Review the SPSS output file, which reports the results of computing the Pearson product-moment correlation coefficient to examine the possible relationship between the number of calories in a brand of beer and its alcohol by volume. Answer the following questions based on your observations of the SPSS output file:

1. Looking at the correlations table, what is the r-value for the correlation between these two variables?
2. Is that r-value statistically significant? What is the 2-tailed significance?
3. Write the results in the following format:  r(df value) = ____, p = _____
