Investigation of influence of test tasks uneven distribution in the center of measuring scale on the latent variables simulation precision
Страницы / Pages: 105-113
Аннотация / Annotation:
In the middle of the last century due to the development of the theory of latent variables it became possible to measure latent variables on a linear scale. In its turn it gave an impulse for conducting research in social systems on advanced level. But till now in this theory there are open-ended issues. One of them is the influence of the uneven distribution of the test tasks on the precision of latent variable simulation. The paper continues a series of articles devoted to the measurement precision of latent variables. This article examines the impact of the uneven distribution of the test tasks in the center of the measuring scale on the deviation of the experimental values of latent variable from computer-simulated ones.
Ключевые слова / Keywords:
Rasch model, measurement of latent variables, test as the measuring tool, distribution of test items.
