SCENARIO

Place Order

You are a Marriage and Family Therapist. In your practice,
you’ve noticed that children seem to be dramatically influenced by
their parent’s marital relationship. You think that changes in
marital relationship can be predictive of a child’s overall life
satisfaction. In order to test this, you collect data from both
children and their parents (n=20). You give the children
in your study the Child Psychological Wellbeing Inventory (CPWI)
and their parents the Marital Satisfaction Survey (MSS). Using the
data below, answer the following questions.

  1. What is the research question?
  2. Calculate the expected CPWI for MSS scores of 102 and 128.
  3. Given that this is a bivariate analysis, what is the
    correlation coefficient (r)?
  4. Report and interpret the 95% confidence interval for the
    correlation.
