https://doi.org/10.17853/1994-5639-2014-7-36-46
Abstract
The objective of the study is to investigate the measurement accuracy of latent variables depending on a number of dichotomous test items and variation range.
Methods: Investigation is based on the simulation experiments.
Results: The authors make recommendations for selecting a number of dichotomous test items and variation range depending on the required measurement precision of latent variables.
Scientific novelty: The research demonstrates statistical correlation between the measurement precision of latent variables and a number of test items and variation range.
Importance for practice: The research results can be used while developing the questionnaires and tests for measuring the latent variables.
