Which group has more confidence in clergy? Explain.

Using ONEWAY procedure, test for a statistically significant difference between a woman’s degree (DEGREE) and number of children (CHILDS). Using degree as the independent variable and number of children as the dependent variable, we want to assess whether there is a relationship between educational attainment and number of children.

Which groups are significantly different from one another? (Hint: Look at the Post Hoc table)

What are the mean ages for the different degree levels? (Hint: Look at the Post Hoc table)

Follow these instructions to make a decision and conclusion:

If p value < alpha level Reject the null hypothesis and conclude that there is a significant difference

If p value > alpha level Fail to reject the null hypothesis and conclude there is not a significant difference.
