STRUCTURAL EQUATION MODELING REAL TIME APPLICATION WITH EXAMPLES BASIC INTRODUCTION- II Latent Vs. Manifest/ Observed Variables in SEM analysis What is Latent & Observed in SEM? 1. SEM consists of two parts ● Measurement model(s) for each latent variable ● Path analysis between the latent and observed variables 2. Variable Labels ● Latent variable factor construct ● Observed variable measured variable manifest variable indicator generally considered endogenous Observed or manifest variables: Latent variables are not observed directly, it follows that they cannot be measured directly. ● The unobserved variable is linked to one that is observable, thereby measurement is possible. ● directly measurable (through questionnaire) ● include measurement error ● The term behaviour is used here in the very broadest sense to include scores on a particular measuring instrument. Examples: 1. Self-report to an attitudinal scale. 2. Scores on achievement test. Upcoming Weeks….. Lecture -3 Structural Equation Modeling (SEM) using AMOS 1.
