Margins | Yes Number | No Number | Total Number |
---|---|---|---|

Negative | 7 (4.6)^{*} | 39 (41.4) | 46 |

Positive | 0 (2.4) | 24 (21.6) | 24 |

Total | 7 | 63 | 70 |

* Numbers in parentheses are calculated.

Note: The observed χ

^{2}= 4.06. If there were an effect at the*P*= .05 level, then the expected χ^{2}= 3.84. Because the observed exceeds the expected, we conclude that the margin type affects the frequency of mild recurrence (*P*= .05). Reject the null hypothesis that the frequencies are the same.
