d.         The IV is length of gestation (preterm vs term vs postterm) using the same multiple birth mothers over time; the DV is blood pressure 10 minutes post delivery.

Answer 1

a) The IVs are ethnicity (Asian, White, African American, Hispanic) and gender (male vs female); the DV is serum cholesterol levels :  Two way ANOVA

b) The IV is smoking status – smokers vs non-smokers; the DV is a health-related hardiness score, measured on a 20-item scale : One way ANOVA

c) The IV is maternal breast feeding status (breastfeeds daily vs doesn’t breastfeed); the DV is a maternal bonding with infant score, measured on a 20-item scale : One way ANOVA

d) The IV is length of gestation (preterm vs term vs postterm) using the same multiple birth mothers over time; the DV is blood pressure 10 minutes post delivery : One way ANOVA
