如果是等距或等比数据,则适合采用单样本t检验。 Example1:研究人员测量一个登记选民样本中每个个体的IQ,然后t检验可以用来评估整个登记选民总体的IQ均值。 Example2:研究人员把已登记的选民样本按性别归类,然后计算男性和女性的人数。这时候,卡方检验适合评估有关总体比例的假设。 E1和E2采用不同方法的原因在于IQ是连...

Example #1 The chi-Square test can tell us whether the proportion of a given number of items in one place based on a random sample is statistically independent of each other. Suppose your company has 10000 pieces of furniture. About one by a tenth of them are distributed over four halls....

A chi-square test (achi-square goodness of fit test) can test whether these observed frequencies are significantly different from what was expected, such as equal frequencies. Example: Handedness and nationality Contingency table of the handedness of a sample of Americans and Canadians ...
