Replicate the results reported in the chapter. Specifically,
review each of the extraction criteria for determining the number
of factors to extract within the engineering, SDQ, and GDS data sets.
Examine the various
extraction criteria using the first author’s identification
with academics (Osborne, 1997) data (which was described briefly and
downloaded for the exercises in Chapter 2). Make a recommendation
for the number of factors that should be extracted from this data.
