![]() Detect consistent patterns of measurement error that can lead to the overall improvement or calibration of the measurement system Determine early in an analysis whether the data are usable for making experimental or treatment decisions Observer reactivity is measurement error caused by an observer's _ that others are evaluating the data he reports.īenefits of assessing the accuracy of data Measurement bias caused by observer expectations can be avoided by using _ observers. Observers _ receive feedback about the extent to which their data confirm or run counter to hypothesized results or treatment goals. _ can be minimized by booster training sessions and feedback on the accuracy and reliability of measurement.Īn observer's _ about predicted or desired results can impair the accuracy and reliability of data. Observer Drift involves _ in the way an observer uses a measurement system over the course of an investigation. Observers should receive systematic training and practice with the measurement system and meet predetermined accuracy and reliability criteria _ collecting data. Most investigations in applied behavior analysis use human observers to measure behavior, and _ is the biggest threat to the accuracy and reliability of data.įactors that contribute to _ include poorly designed measurement systems, inadequate observer training, and expectations about what the data should look like. Measurement artifacts are data that give an unwarranted or misleading picture of the behavior because of _.ĭiscontinuous measurement, poorly scheduled observations, and insensitive or limiting measurement scales are common causes of _. Measuring a dimension of the behavior that is ill suited for, or irrelevant to, the reason for measuring the behavior compromises validity Indirect Measurement threatens validity because it requires the researcher or practitioner to _ about the relationship between the measures obtained and the actual behavior of interest.Ī researcher who uses _ must provide evidence that the behavior measured directly reflects, in some reliable and meaningful way, something about the behavior for which the researcher wishes to draw conclusions. Indirect Measurement involves measuring behavior that is _ from the behavior of interest. Measurement is _ when it yields the same values across repeated measurement of the same event. ![]() Measurement is _ when observed values, the data produced by measuring an event, match the true state, or true values, of the event. Ensuring that the data are representative of the behavior under conditions and during times most relevant to the reason for measuring it. measuring a dimension of the target behavior relevant to the question or concern about the behavior measuring directly a socially significant target behavior Three Element of Valid Measurement in ABA To be most useful for science, measurement must be _.
