Estimating the degree to which the risk of an event or outcome is increased or decreased based on a condition is a common statistical problem. In the healthcare and insurance sectors, measures of association such as odds ratios and relative risk ratios are key indicators of risk and treatment efficacy. For many users though, understanding the differences between odds ratios and relative risk values can be a challenge. Moreover, in SPSS Statistics, deciphering these values correctly can be confusing as the variable arrangement and category order affect the calculation of the ratios and their interpretation. In this video, Jarlath Quinn explains how these values are calculated and how users can code and arrange the variables so that their interpretation is as straightforward as possible.
