METHODS OF HYPOTHESIS TESTING.

METHODS OF HYPOTHESIS TESTING.

After collection of data is valid or not, hypothesis testing is performed. After testing the hypothesis is the researcher decides either to accept or reject the hypothesis. There are two methods to deal with the hypothesis testing:

1.     Parametric test :- It is based on the properties of the parent population from which we draw sample. Parent population means the original population.

For example: The assumption are taken from this population only. It is  the normal population. The sample size is large and the parameters like means, etc. should be accurate.

2.     Non-Parametric test :– Due to some situations researcher does not make assumption. Thus they are called non-parametric tests. These tests are based on the measurement equivalent to at least an interval scale. Non-parametric tests need more observation the parametric test.
