The article considers the features of the formalization of a latent variable. The key attributes of the latent variable, – validity and reliability, – are considered. An example of measuring the latent variable "emotional well-being of younger schoolchildren" on a linear scale is shown. The effectiveness of the primary school education program has been quantified.
The article shows the relevance of using the theory of measurement of latent variables in social systems. This is due to the fact that many variables in social systems are latent. Scales of estimation of latent variables are considered. A key aspect of the construction of the theory of latent variables is invariance both with respect to objects and indicators. It should be noted that this theory was developed by the Danish scientist Georg Rasch to solve problems in the field of education.
