If you go back to Exercise 16.2, you will see that it really forms a 2 3 2 factorial. Run the factorial analysis and interpret the results. (The data are reproduced here.)
Answer to relevant QuestionsIn Exercise 16.3 you ran a test between Groups 1 and 3 combined versus Groups 2 and 4 combined. How does that test compare to testing the main effect of Location in Exercise 17.16? Is there any difference? Calculate d^ for the difference due to education in Exercise 17.19. Next ignore the normal birth weight condition in Exercise 17.19 and calculate d^ for comparing the two low-birth weight groups. By comparing the formulae for η2 and ω2, tell when these two different statistics would be in close agreement and when they would disagree noticeably. In a study of mother2infant interaction, mothers are rated by trained observers on the quality of their interactions with their infants. Mothers were classified on the basis of whether this was their first child (primiparous ...Run a repeated measures analysis of variance on the data in Exercise 18.1 and explain your results.
