On the utility of aPost Hoc correction procedure for one-zero sampling duration estimates

  • Hoi K. Suen
Article

Abstract

Numerous previous studies have shown that one-zero sampling in direct observation systematically overestimates behavioral durations. Apost hoc correction procedure has been proposed and demonstrated to be capable of removing most of the systematic errors found in one-zero duration estimates. However, the remaining errors for some individual observation sessions can still be quite substantial in practical terms. In this paper, the condition under which thepost hoc correction procedure will produce results with negligible systematic errors in one-zero duration estimates is identified.
