Abstract

"Continuous and discontinuous data collection methods were compared in the context of discrete trial programming. Archival data sets were analyzed using trial sampling techniques (first five trials, first three trials, and first trial only) and session sampling techniques (every other session, every third session, and every fifth session). Results showed trial sampling to systematically underestimate the number of sessions and days to mastery and overestimate the number of sessions and days to the first independent response. Session sampling systematically overestimated sessions and days to mastery and sessions and days to the first independent response. A time-savings analysis was included to empirically test how much time would be saved by using the sampling methods. Results suggested that data sampling would produce relatively minimal time savings."
