Setting Time Limits on Tests
Peer reviewed Peer reviewed

van der Linden, Wim J. – Applied Psychological Measurement, 2011
It is shown how the time limit on a test can be set to control the probability of a test taker running out of time before completing it. The probability is derived from the item parameters in the lognormal model for response times. Examples of curves representing the probability of running out of time on a test with given parameters as a function…

Testing for Local Dependence in Rasch's Multiplicative Gamma Model for Speed Tests
Peer reviewed Peer reviewed
Direct linkDirect link
Jansen, Margo G. H. – Journal of Educational and Behavioral Statistics, 2007
The author considers a latent trait model for the response time on a (set of) pure speed test(s), the multiplicative gamma model (MGM), which is based on the assumption that the test response times are approximately gamma distributed, with known index parameters and scale parameters depending on subject ability and test difficulty parameters. Like…

Checking the Assumptions of Rasch's Model for Speed Tests
Peer reviewed Peer reviewed
Direct linkDirect link
Jansen, M. G. H.; Glas, C. A. W. – Psychometrika, 2005
Two new tests for a model for the response times on pure speed tests by Rasch (1960) are proposed. The model is based on the assumption that the test response times are approximately gamma distributed, with known index parameters and unknown rate parameters. The rate parameters are decomposed in a subject ability parameter and a test difficulty…
