抽樣誤差sampling error: 1. 樣本結果與估計的樣本特徵之間的差異 2. 由樣本的隨機性引起的那部分參數的總體估計誤差。 簡單來說就是只做部分抽樣,一定都會跟總體樣本會有些微誤差,如果你抽得越多,誤差就越小,如果能做到普查就不會產生誤差。 Sampling error: 1. the difference between a sample’s result and the population characteristic that is being estimated 2. that part of the overall estimation error of a parameter (see Appendix II) caused by the random nature of the sample.
