Choose a DV and two IVs to perform a 3 x 3 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 basic statistics of the IVs and DV (e.g. Mean, SD). (Hint: Only
one-way listing of variables is needed. Do NOT copy and paste SPSS output
directly). Number and name the table.
c)
Copy and paste the ANOVA summary outputs
directly from SPSS (only include the relevant parts). Then, based on the SPSS outputs make an ANOVA
Summary table on your own. Number and name the table.
d)
From the F-table, obtain 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
e)
Test the statistical
significance for all effects. Report the results in simple English 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.
(Note:
Post-hoc tests may be conducted only where appropriate.)
f)
Plot a graph to show the
two-way analysis (Hint: You may need to edit the SPSS graph, or use other
software such as Excel to plot the graph). Number and name the Figure in APA format.
Reminder
Use MS-Word to print your work; do not print your
work directly from SPSS outputs. Use Times New Roman, font size 12, double-line
spacing.
