Statistical analysis.

Statistical method	Notes
Cronbach’s alpha coefficient	Validated the reliability of the instrument
The Kaiser-Meyer-Olkin (KMO) test	Checking if the data is suitable for factoring
Exploratory factor analysis with varimax rotation	Separating factors that are orthogonal to each other (they have 0 correlation)
Principal component analysis	Standard extraction model
Pearson’s correlation	Used on age variable because it is a continuous variable
Spearman’s rank correlation	Used on education variable because it is of ordinal type
