WebSep 1, 2016 · Introduction. This module will continue the discussion of hypothesis testing, where a specific statement or hypothesis is generated about a population parameter, and sample statistics are used to assess the likelihood that the hypothesis is true. The hypothesis is based on available information and the investigator's belief about the … WebSelecting the correct hypothesis test for variation is relatively simple. We need only to know if the data is normal and if there are two or more samples (or data sets). In the above example, there are only two samples, Alentus and Host Monster. The flow chart below is a map to the correct test. The first step is a determination of normality.
