SEM Sample Size Calculator SEM Sample Size Calculator Estimate the minimum sample size for your Structural Equation Modelling (SEM) project using rule-based and literature-backed methods. Choose SEM Method: Covariance-Based SEM (CB-SEM) Partial Least Squares SEM (PLS-SEM) Number of Predictors: Estimated Number of Indicators: Estimated Parameters to Estimate: Calculate 📌 Example 1: CB-SEM Scenario: 4 latent variables, each with 5 indicators → 20 indicators. Estimated 30 model parameters. Steps: Choose CB-SEM, enter Predictors: 4, Indicators: 20, Parameters: 30. Result: 300 samples (Kline, 2016) 📌 Example 2: PLS-SEM Scenario: Most complex latent variable has 6 predictors. Total 18 indicators. Steps: Choose PLS-SEM, enter Predictors: 6, Indicators: 18, Parameters: 30. Result: 100 samples minimum (Hair et al.,...
