- The basic logic of hypothesis testing has been presented somewhat informally in the sections on ruling out chance as an explanation and the null hypothesisin this section the logic will be presented in more detail and more formally.
- In statistics, hypothesis testing is a confirmatory analysis of statistical data to make yes or no decisions a hypothesis test analyses the results of the null hypothesis and the alternative hypothesis of a population.
- If it isn't true, the analyst formulates a new hypothesis to be tested, repeating the process until data reveals a true hypothesis testing a statistical hypothesis the next step is to formulate an analysis plan, which outlines how the data will be evaluated.
The five-step hypothesis testing procedure is a method for testing a hypothesis, a proposed answer of solution for the reason an occurrence is happening also referred to as statistical hypothesis. Before moving onto the second step of the hypothesis testing process, we need to take you on a brief detour to explain why you need to run hypothesis testing at all.
