  • 只根据部分案例的特质推论整个群体的一般性特质（合成谬误）
  • 只根据部分特例否定一般性通则（逆偶例谬误）
  • 只根据部分支持的证据支持一个论点（单方论证）

Sampling bias 以偏概全

Simple pedigree example of sampling bias
Example of biased sample: as of June 2008 55% of web browsers (Internet Explorer) in use did not pass the Acid2 test. Due to the nature of the test, the sample consisted mostly of web developers.[15]

In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population are less likely to be included than others. It results in a biased sample, a non-random sample of a population (or non-human factors) in which all individuals, or instances, were not equally likely to have been selected. If this is not accounted for, results can be erroneously attributed to the phenomenon under study rather than to the method of sampling.
