Ordinal data are widely available to educational researchers. One of the most commonly used models to analyze ordinal data is the proportional odds (PO) model, which is also known as the cumulative odds model. However, when the research interest is focused on a particular category rather than at or below that category, given that an individual must pass through a lower category before achieving a higher level, the continuation ratio model (Fienberg, 1980; Hardin & Hilbe, 2007; Long & Freese, 2006) is a more appropriate choice than the proportional odds model.
