What do you mean by hypothesis testing? Describethe various ) steps involved in hypothesis testing?
Answers
Hypothesis testing is a scientific process of testing whether or not the hypothesis is plausible. The following steps are involved in hypothesis testing:
The first step is to state the null and alternative hypothesis clearly. The null and alternative hypothesis in hypothesis testing can be a one tailed or two tailed test.
The second step is to determine the test size. This means that the researcher decides whether a test should be one tailed or two tailed to get the right critical value and the rejection region.
The third step is to compute the test statistic and the probability value. This step of the hypothesis testing also involves the construction of the confidence interval depending upon the testing approach.
The fourth step involves the decision making step. This step of hypothesis testing helps the researcher reject or accept the null hypothesis by making comparisons between the subjective criterion from the second step and the objective test statistic or the probability value from the third step.
The fifth step is to draw a conclusion about the data and interpret the results obtained from the data.
There are basically three approaches to hypothesis testing. The researcher should note that all three approaches require different subject criteria and objective statistics, but all three approaches give the same conclusion.
