Download the engineering, SDQ, and/or GDS data from the book website. Replicate the results reported in the chapter. Examine the extraction methods to see which one provides the best extraction for each data set.

Download data from an early version of one of the first author’s early studies on identification with academics (Osborne, 1997). This instrument was intended to be a measure of identification with academics (the extent to which a student defines himself or herself as a student as part of self-concept). There were supposed to be three scales, measured on a scale of 1 (disagree strongly) to 7 (agree strongly): a) centrality of academics to self (items 1, 4, 7, 9, 10, 11, 15, 16, 18, 19, 20, 21); b) feelings of discrimination (2, 3, 6), and; c) diagnosticity of academic outcomes (5, 8, 12, 13, 14, 17). Examine the extraction methods and determine which one provides the best extraction for this data set.
