2. The NELS data include a series of items (ByS44a to ByS44m) designed to assess students’ self-esteem and locus of control. Choose several or all of these items that you believe best measure self-esteem and locus of control and subject them to confirmatory factor analysis. First use SPSS (or another general statistical program) to create a matrix for analysis in Amos (or one of the other programs). Then analyze your model using this matrix. I recommend using the matrix for analysis in order to temporarily avoid dealing with missing data in Amos.
