Statswork (Statswork.com), Lecture:2 – Basic concepts of Latent, Manifest and Observed Variables using in SEM analysis. SEM consists of two parts: 1. Measurement model(s) for each latent variable 2.2. Path analysis between the latent and observed variables. Latent Variables: These phenomena are termed as latent variables, or common factors. Examples of latent variables: ·Psychology: Self concept and Motivation. ·Education:Verbal ability& Teacher Expectancy. Manifest and Observed Variables: The unobserved variable is linked to one that is observable, thereby  measurement is  possible. Examples: ·Self-report to an attitudinal scale. ·Scores on achievement test. Watch more.

Structural Equation Modelling (SEM) is a widely used technique in statistics to primarily study relationships based on structures. It encompasses various models involving mathematics, statistical procedures etc. This technique is known to be extremely effective when it comes to measuring latent constructs. Many of us might be familiar with concepts like Multiple Regression Analysis and Factor Analysis, this in simple term, is a combination of these techniques. It is, in fact, a mere extension of General Linear Model. You can test a bunch of regression techniques at the same time.
