Abstract:
Research indicates that momentary time sampling (MTS) is often the best interval-measurement system when observing duration of behavior. Several recent studies recommended considering mean duration of target behavior, as well as durations of measurement intervals and observation sessions, to minimize measurement error in MTS. This report describes the steps we used to minimize measurement error in a single-case design research study. Further, we detail our methods for monitoring and reporting MTS measurement error across conditions by intermittently collecting and analyzing duration per occurrence measurements.

Systematic Error: Methodological and Sampling Errors
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...
