The mean difference is significant at the 0.05 level.
a. What was the mean for each group?
b. Report the ANOVA in APA style.
c. Was the test significant? If so which groups were different from each other
and in what way?
Transcribed Image Text:4. Maternal role adaptation was compared in a group of mothers of low birth-weight
(LBW) infants who had been in an experimental intervention, mothers of LBW
infants who were in a control group, and mothers of full-term infants. Using SPSS,
researchers performed an ANOVA to see if there is a difference in adaptation
between the groups. They got the following results:
