Assignment - CFA - HANDS-ON
Please return to your assignment (see below), and use the same dataset for constructing and estimating a CFA model (in AMOS), which mimics the factor structure you identified in the EFA process (with varix rotation).
1. What are the fit indices? Are they good?
2. What are the correlations between latent variables (if any)?
3. Draw a diagram of the model
4. What is the highest modification index? What does it tell us?
The paper is usually between 1 and 3 pages long.
Assignment Expectations -
1. Able to run CFA procedures in AMOS.
2. Able to read CFA results in AMOS.
3. Able to effectively and efficiently describe CFA results in research.
(Below instructions) - The enclosed dataset (file attached) - wiscsem.sav is an SPSS file containing the subscale scores for the Weschler Intelligence Scale for Children. The first two columns are subject code and age. The rest include scores on different areas of the exam.
1. Run exploratory factor analysis (principal components, no rotation) on the data. How many meaningful factors will you retain? Interpret them and give them names.
2. Run exploratory factor analysis (principal components, WITH Varimax rotation) on the data. How many meaningful factors will you retain? Interpret them and give them names.
3. Run exploratory factor analysis (principal components, WITH Promax rotation) on the data. How many meaningful factors will you retain? What is the correlation between the factors? Interpret them and give them names.
Assignment Expectations -
1. Be able to run different variants of EFA
2. Develop critical thinking regarding EFA.
