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 an...
