Question

1. Write up the results from this analysis using APA format. Make sure you include each group mean (and SD) exam score, the correct F stat with the correct degrees of freedom and p-value, decision regarding the null, and the follow-up comparisons (if necessary). Use the example in the SPSS ANOVA lecture to help guide you. [3 points]

Answer 1

Answer

From the given data output table, it is clear that the result for ANOVA test is significant, i.e. p value is less than 0.05 significance level, which shows that there is a significant difference between at least one pair of instructors. Turkey HSD test shown us that there is a significant difference only between Miller and field

Using APA format, we can write it as

An analysis of variance has showed us that the result for hypothetical exam scores between four instructors was significant, F(2,77) = 4.810 , p value = 0.011, rejecting the null hypothesis. Turkey HSD test shown us that there is a significant difference only between Miller and field, p value = 0.009
