  • * Numbers in parentheses are calculated.

  • Note: The observed χ2 = 0.99. If there were an effect at the P = .25 level, then the expected χ2 = 1.32; and at the P = .05 level, the expected χ2 = 3.841. Because the observed does not exceed the expected, the type of margin does not affect the frequency of no recurrence (P > .25). Accept the null hypothesis that the frequencies are the same.
