Structural equation model
Contributed by: Grainger
  • 1. A structural equation model (SEM) is a statistical technique used to test and validate complex relationships between variables. It is a powerful tool commonly used in social sciences, psychology, economics, and other fields to study causal relationships among factors. SEM allows researchers to model both observed and unobserved variables, known as latent variables, and to quantify the direct and indirect effects of one variable on another. By specifying multiple interrelated equations, SEM helps researchers understand the underlying mechanisms and pathways through which variables influence each other. This method provides valuable insights into complex systems and can help inform theoretical models, make predictions, and guide decision-making in various research domains.

    In SEM, what does the term 'exogenous variable' refer to?
A) Variable not predicted by other variables in the model
B) Variable with indirect effect only
C) Variable with direct causal effect
D) Variable affected by measurement errors
  • 2. What is the purpose of confirmatory factor analysis in SEM?
A) Assess reliability and validity of measurement instruments
B) Analyze non-linear relationships
C) Predict future outcomes
D) Study causal relationships between variables

C) When an independent variable is correlated with the error term of another variable
D) Measurement error accumulation
  • 12. What does 'model identification' in SEM refer to?
A) Ensuring the unique estimation of model parameters with the given data
B) Interpretation of fit indices
C) Optimization algorithm selection
