PART 1: SPSS Questions
Note: For all the following
questions, assume that the DV is normally distributed.
Q1. You want to assess whether
self-acceptance scores (variable tsa) vary according to personality types.
State null and alternative hypotheses.
Carry out the test. Is the homogeneity of variance
assumption fulfilled?
Report and interpret the results.
Report post-hoc tests if relevant.
Q2. You want to assess whether
self-control scores (variable tsc) vary according to personality types.
State null and alternative hypotheses.
Carry out the test. Is the homogeneity of variance
assumption fulfilled?
Report and interpret the results.
Report post-hoc tests if relevant.
Q3. You want to assess whether empathy
scores (variable tem) vary according to personality types.
State null and alternative hypotheses.
Carry out the test. Is the homogeneity of variance
assumption fulfilled?
Report and interpret the results.
Report post-hoc tests if relevant.
PART 2: Non-SPSS Questions
Q4. If
between-group differences are larger than within-group differences, then the
F-ratio is likely to be higher, thus results are more likely to be
statistically significant. True or false?
Q5. In ANOVA,
what approximate value can we expect to obtain for the F-ratio when the null
hypothesis is true? Explain your answer.
Q6. You
conduct an ANOVA, and get p = .07 for the Levene test. Does this mean that you
reject or accept the null hypothesis for the homogeneity of variance postulate?
Explain more specifically what this result means.
