news. If you create conditions incompatible with life, the program lets you know your patient is dead, this is the MacMan equivalent of crashing your airplane in a flight simulator, and should this happen you merely start again, because there is no equivalent to reversing the program and resurrecting the dead. Some of the experiment options include: cutting the buffer nerves, resetting barorece...

متن کاملCTT and IRT 1 Test Construction using CTT and IRT with Unrepresentative Samples
We compare test construction using CTT and IRT in several sample sizes (from N=20 to N=5000) and degrees of representativeness (represented by selecting the top 20%, 40%, 60%, 80% or 100% of a population) using a Monte-Carlo simulation design. Little support was found for our hypothesis that IRT would outperform CTT in building informative tests, especially in large or unrepresentative samples....
متن کاملGender Differences in Learning the SPSS-Software
In the literature it is often assumed that females are at a disadvantage when working with the computer. Whereas differences could be found in attitudes towards computers (Whitley, 1997) there are only few studies examining performance. As gender per se can not explain performance differences, we used the cognitive-motivational process model (Vollmeyer & Rheinberg, 1999, 2000) to find possible ...
متن کاملItem Bias Detection Using Loglinear Irt
A method is proposed for the detection of item bias with respect to observed or unobserved subgroups. The method uses quasi-loglinear models for the incomplete subgroup x test score x Item 1 × • • • x item k contingency table. If subgroup membership is unknown the models are Haberman's incomplete-latent-class models. The (conditional) Rasch model is formulated as a quasi-loglinear model. The pa...
