- Psychology students learning exploratory factor analysis
- Worth noticing
- The example uses six indicators and explicitly distinguishes simulated population settings from real instrument validation.
Field notes
The simulation treats each row as a person and each column as a continuous score, with configurable loadings controlling how strongly indicators share a dimension. The page distinguishes the population design from the generated sample and notes that the same seed behaves differently in its browser generator and R. Its worked example also cautions that a clear simulated result does not establish the validity of a real instrument.
