Is there a difference in marital satisfaction scores among the three time periods?
option a and c

Repeated Measures ANOVA
one-way ANOVA
options B and C
Question 6 of 11
The null hypothesis for this for the Repeated Measures ANOVA states that...
there is no significant difference among any of the time periods
there is a significant difference between time periods
the group are statistically nonequivalent
options a and c
Question 7 of 11
The alternative hypothesis states that...
there is no significant difference between groups
the group are statistically equivalent
there is a significant difference between at least two of the time periods
all of the above
Question 8 of 11
In a within-groups design, we are...
assessing differences between different groups of subjects
