I received questions about the second part of Question 2a – what kind of research are you looking for?
Some research looks at just one predictive factor at a time – e.g. that people who marry young are more likely to get divorced.
Research with more nuance looks at two or more factors. In class, we studied a graph that showed the divorce percentage of people who married young across the length of the marriage. But there was more than one line: that rate was calculated for groups defined by the second factor, race/ethnicity. So we were looking at two factors at once: early marriage and race/ethnicity. The impact of early marriage was much stronger in some race/ethnic groups than others.
So divorce was the outcome, and the two factors were age at marriage and race/ethnicity.
