χ² = 64.89, df = 18, p < 0.001
*Combining teaching and research and teaching and departmental affairs to produce weights for ties from 1 to 3 yields χ² = 40.38, df = 12, p < 0.001. Largest contributors to χ² are Bio1 (more 2’s and 3’s and fewer 1’s than expected), Bio3 (more 3’s and fewer 1’s and 2’s than expected), and Chem3 (more 1’s and 2’s and fewer 3’s than expected)
