paired use Mcnemar test; otherwise choose Pearson or Fisher exact test. For
example http://yatani.jp/HCIstats/ChiSquare
What do they mean by "paired data"? Any discussion is welcome. |

google Mcnemar test
看个例子就清楚了
mcnemar测的不是independence. 测的是proportion是否一样 |
w*******9 发帖数: 1433 | 3 Thanks ningyan you reassured me --- the essential difference is they're
testing different things. It's misleading to decide which method to use by
telling whether the data is "paired" or not.
For example, why 左眼和右眼 is considered paired, but cancer status and
smoking status (from the same subject) is not considered "paired".
