Given the context of comparing more than two groups (freshman, sophomore, junior, or senior) on a categorical outcome (closeted or out), a Chi-square test for independence is appropriate. For a Chi-square test with a p level of 0.05 and degrees of freedom equal to the number of groups minus one (in this case, 4 - 1 = 3), the critical value is 7.815.
