2. Although the EFA has suggested possible subscales within the geoscience attitude survey, these subscales may not have high internal consistency.

Again using the data set “Geoscience Attitudes.sav,” compute coefficient alpha for each of the emergent factors.

a. What is the reliability of each of the factors?

b. Would deleting one or more items from a factor considerably improve internal consistency reliability? If so, delete these item(s) and recompute the reliability of the factor.

c. Which factors do you believe achieve a sufficiently high alpha to be considered viable subscales for use in research?
