Sample answer:
Factor Analysis and Scale Development Experience
My extensive experience in factor analysis and scale development encompasses various domains:
Factor Analysis:
- Conducted exploratory factor analyses (EFA) to identify underlying constructs and patterns in large datasets.
- Utilized principal component analysis (PCA), maximum likelihood estimation (MLE), and oblique rotation methods.
- Evaluated factor solutions based on communalities, scree plots, eigenvalues, and factor loadings.
- Determined the number of factors through statistical criteria (e.g., Kaiser-Meyer-Olkin measure of sampling adequacy, Scree test) and theoretical considerations.
Scale Development:
- Developed and validated Likert-type and semantic differential scales for measuring psychological constructs.
- Utilized item analysis techniques (e.g., item discrimination, homogeneity) to assess item quality and reliability.
- Performed internal consistency reliability analysis (e.g., Cronbach’s alpha, omega) to determine the extent to which items within a scale measure the same construct.
- Conducted test-retest reliability analysis to e… Read full answer
