配对t检验(Paired Sample T-Test):用两个配对样本中各对观测值的差值均数和假设的差值进行比较,来检验以下几种情形: 1,同一受试对象或两个同质受试对象接受两种不同处理后的差异;2,同一受试对象接受处理前后的差异。 配对t检验的本质是先计算成对观测值之间的差异的均值,之后执行单样本t检验。 (d为每对数据的...

Location tests, such asz-test and one-samplet-test, test whether sample data comes from a population with a particular mean or median. Test two or more sets of sample data for the same location value using a two-samplet-test or multiple comparison test. ...
Create a Visual Aid of the Test To simplify the testing process, break down the process into4small steps. Create a table similar to the one below and begin by completing the top two quadrants. The bottom-left contains the results from the test and then converting those numbers into meaning...
