Question:
173 Socialization of graduate students. Teaching Sociology
(July 1995) developed a model for the professional socialization of graduate students working toward a Ph.D. in sociology. One of the dependent variables modeled was professional confidence y , measured on a five-point scale.
The model included over 20 independent variables and was fitted to data collected on a sample of 309 sociology graduate students. One concern was whether multicollinearity existed in the data. A matrix of Pearson product moment correlations for 10 of the independent variables is shown below. [ Note: Each entry in the table is the correlation coefficient r between the variable in the corresponding row and 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 you found in part a are left in the model? Explain.
