Hypothesis is usually considered as the principal instrument in research. It plays a major role in research. Its main function is to suggest new experiments and observations. It occupies a very small space in the thesis. A researcher cannot proceed in the research work without formulating one or more than one hypothesis. Hypothesis brings clarity, specificity and focus to a research problem. There are two types of hypothesis which are called the Null Hypothesis and the Alternative Hypothesis. There are four steps in hypothesis testing. After getting the results, the researcher tests whether the collected facts support the hypothesis formulated or not. There exist a number of statistical tools like ttest, F-test, chi-square test, D-W test, etc., to test the validity of hypothesis. Hypothesis testing shows whether the hypothesis should be accepted or rejected. It has been rightly said that “You torture the data until they confess”. This paper include the introduction, steps of hypothesis testing, function of hypothesis and testing of hypothesis.
