NURS 7631

Repeated-Measures Homework

Use the data file "NICUdata.sav"

These data are from a trial of 3 different interventions (IV) in the Neonatal Intensive Care Unit for stable neonates from Gestational Age 30 to 34 weeks.

• Condition 1: Nonnutritive sucking (HR_1)
• Condition 2: Nonnutritive sucking + Rocking (HR_2)
• Condition 3: Rocking (HR_3)

The DV is heart rate. The 12 participating infants were randomly assigned to six different order combinations of the three interventions. After 10 minutes of each intervention, heart rate was monitored for 5 and the mean 5-min heart rate recorded for each infant after each intervention. The dataset also contains the variable "Gender" and "GestWks."

Using a repeated measures ANOVA (RANOVA), answer the following questions:

1. Is there a difference in heart rate by intervention?
2. Is the assumption of sphericity met in the data?
3. Do boys and girls differ in their heart rate response to the interventions?
4. Produce a graph that shows the difference in means across the 3 interventions for boys and girls.
