Data analysis methods in optometry Part 3: the analysis of frequencies and proportions

Research output: Contribution to specialist publicationArticle

Abstract

In some studies, the data are not measurements but comprise counts or frequencies of particular events. In such cases, an investigator may be interested in whether one specific event happens more frequently than another or whether an event occurs with a frequency predicted by a scientific model.
