title: Describing behavior with ratios of count and time.
abstract: Describing behavior with ratios of count and time is a popular measurement tactic in the field of behavior analysis. The paper examines some count and time ratios in order to determine what about behavior each describes and why one ratio may sometimes be more useful than another. In addition, the paper briefly considers some terminological issues, derived quantities, dimensional analysis, some advantages and disadvantages of ratios, and selection of useful quantities for measurement.
