WebOct 1, 2016 · Instantaneous sampling is expected to more accurately reflect true values when (1) sampling frequency increases, (2) a behavior occurs in relatively long bouts, and (3) intervals between bouts are relatively long ( Martin and Bateson, 2007 ), as instantaneous samples would be less likely to miss bouts and the intervals between them. WebThis protocol is intended to imitate a series of instantaneous photos of the study animals, with successive photos taken at a specified time interval. Since we can’t ...
