Teaching Sociology (July 1995) developed a model for i the professional socialization of graduate students working toward their doctorate. One of the dependent variables modeled was professional confidence. y, measured on a 5-point scale. The model included over 20 independent variables and was fitted to data collected for a 1 sample of 309 graduate students. One concern is whet he^ multicollinearity exists in the data. A matrix of Pearson product moment correlations for ten of the independent variables is shown on page 622. [Note: Each entry in the table is the correlation coefficient r between the variable in the corresponding row and corresponding column.]
a. Examine the correlation matrix and find the independent variables that are moderately or highly correlated.
b. What modeling problems may occur if the variables, part a, are left in the model? Explain
