How to report a exploratory factor analysis

What is stated first?
The total number of students that completed the questionaire and how many items were in the questionaire
1 of 20
What is next stated?
What the questionnaire was about
2 of 20
What was then stated?
What the questionnaire involved
3 of 20
What is then stated?
The means and standard deviations
4 of 20
What is then stated about the skew
What direction the skew was going in and whether this was equal across all items
5 of 20
However, what would the skew not do?
Affect the results due to a large sample size
6 of 20
What is then considered?
Pre-analysis checks
7 of 20
What is the first preanalysis check?
The ratio of participants to items (>95:1) and the minimum number of participants (100) were exceeded
8 of 20
What is the second preanalysis check
What the communalities number was and the number of participants exceeded required (500) minimum
9 of 20
What is then stated?
The Kaiser Meyer Olkin test, measure the sampling adequacy exceeded minimum (.5) indicating that the correlations had some variability
10 of 20
What test had to be found significant?
Bartlett's test of sphericity was significant (p
11 of 20
What is the final exploratory factor analysis solution?
Varimax (Orthogonal rotation) indicated that a two factor model best explained the observed pattern of correlations.
12 of 20
What is the minimum recommended?
Ratio of items to factors (4:1) was met and the minimum required ratio of participants to factors was exceeded (>380:1)
13 of 20
What is then stated?
Factor extraction
14 of 20
What rule?
K1 rule, scree plot and parallel analysis
15 of 20
What would be indicated from these tests?
What solution would be suitable
16 of 20
How would you know?
The eigenvalues would be above 1
17 of 20
What is the point of inflection?
Scree test
18 of 20
The observed eigenvalues what?
Stopped exceeding the random eigenvalues at 2 factors (Parallel analysis)
19 of 20
What did the first extracted factor account for?
41.6% of the variance and second 15.1%, thus two factors together account for 56.7% of the observed variability
