In hypothesis testing, what is the difference between a two-sample t-test and a two-sample z-test? Comparing the answers to (a) and (b), for what range of values of t statistics would the hypothesis test conclusion differ between using ...

Types of Tests. There are two main types: one-way and two-way. Two-way tests can be with or without replication. One-way ANOVA between groups: used when you want to testtwo groupsto see if there’s a difference between them.
The Wilcoxon signed-rank test is used to compare two related samples or to check the difference in multiple measurements of the same sample to determine whether there exists a difference in their population mean ranks. The overall task is to see if there is a difference between two sets of ...
Examples of tests that can be conducted as z-tests include a one-sample location test, a two-sample location test, a paired difference test, and a maximum likelihood estimate. Z-tests are closely related to t-tests, but t-tests are best performed when an experiment has a small sample siz...
