Assignment:
Short Assignment: Two-way Factorial Design ANOVA
Note: Use the GSS data file for this assignment.
Choose a DV and two IVs to perform a 3 x 4 factorial design ANOVA. You may modify the data to fit the data analysis requirement (e.g. regrouping "Age" into Age Groups). Make sure you have coded/recoded appropriately.
a) Name the IVs and DV and describe briefly the method of coding/recoding where necessary.
b) In APA format, make a Table to display the descriptive statistics (Mean, SD or CI). Number and name the Table.
c) Copy and paste the ANOVA summary outputs directly from SPSS (only include the relevant parts).
d) What are the F-critical values for testing the main effects and interaction effects? Quote both .05 and .01 significance levels in the following format, for example:
Critical F-values of Factor A Main Effect:
FC (2, 124) = 3.07, p < .05="">
FC (2, 124) = 4.78, p < .01="">
e) Test the statistical significance for all effects. Report the results in simple statements in APA format, for example,
Chinese people reported significantly higher collectivism than the other two ethnic groups did, F(2, 229) = 5.25, p < 01.="">
f) Plot a graph by hand to show the two-way analysis. Number and name the Figure. (Do not just copy and paste the SPSS output.)
