An Exponentially Weighted Moving Average Procedure for Detecting Back Random Responding Behavior
Peer reviewed Peer reviewed
Direct linkDirect link
He, Yinhong – Journal of Educational Measurement, 2023
Back random responding (BRR) behavior is one of the commonly observed careless response behaviors. Accurately detecting BRR behavior can improve test validities. Yu and Cheng (2019) showed that the change point analysis (CPA) procedure based on weighted residual (CPA-WR) performed well in detecting BRR. Compared with the CPA procedure, the…

An Application of Item Response Time: The Effort-Moderated IRT Model
Peer reviewed Peer reviewed
Direct linkDirect link
Wise, Steven L.; DeMars, Christine E. – Journal of Educational Measurement, 2006
The validity of inferences based on achievement test scores is dependent on the amount of effort that examinees put forth while taking the test. With low-stakes tests, for which this problem is particularly prevalent, there is a consequent need for psychometric models that can take into account differing levels of examinee effort. This article…
