Clearly, a larger sample provides more relevant information, and as a result a more accurate estimation and better statistical judgement regarding test of hypotheses. Hypothesis testing is a procedure for reaching a probabilistic conclusive decision about ...

The goal of testing an hypothesis is to test some hypothesis about the parent population from which the sample is drawn. If the data is normally distributed, parametric tests are to be used, otherwise, non-parametric tests n ...
