After analyzing the data, the researcher is in a position to test the hypotheses, if any, has been formulated.

Do the facts support the hypotheses or they happen to be contrary? This is the usual question which should be answered while testing hypotheses. Various tests, such as Chi square test, t-test, F-test, have been developed for the purpose.

The hypotheses may be tested through the use of one or more of such tests, depending upon the nature and object of research inquiry.

Hypothesis-testing will result in either accepting the hypothesis or in rejecting it.

If the researcher had no hypotheses to start with, generalizations established on the basis of data may be used as hypotheses by other researches.
