Hypothesis test is a formal produce for investigatiny our ideas about the word using statistic. It is most often useb by scientists to test specific productions, called hypothesis, that arrives from theories.

There are 5 main steps.

1) State research hypothesis as a null hypothesis (

2) Collect data in a way designed to test the hypothesis.

3) Perfom am appropriate statistical test.

4) Decide whether to reject or fail to reject null hypothesis.

5) Present the finding in results and discuss on section.
