Factor Analysis in Jamovi
- Go to "Factor" → "Principal Component Analysis".
- Move your items (variables) into the analysis box.
- Check Scree plot.
- Under Rotation, select Varimax.
- Number of Components->Based on eigenvalue
- HIDE LOADINGS BELOW->1
- In the Loadings table, look for items with loadings above .5 on a factor — these are your strong items.
Describe the results of the exploratory factor analysis:
- How many factors were extracted
- List the factors in a table
- Can you subjectively make sense of how the items loaded on each factor (what does each factor mean?)
- After examining the data, how many factors you would retain in your final solution? Explain your reasoning for including or excluding each factor.
- Try your best at writing up the results section
