  1. As not all informants have answered all demographic questions, sub-sample numbers do not always add up to the sum total.
  2. 1 One-way ANOVA. Scheffe's post-hoc tests: Inmates statistically different from prison employees and students at the .05-level
  3. 2 One-way ANOVA. Scheffe's post-hoc tests: Business economics students statistically different from nursing students at the .05-level
