Hypothesis Testing

Hypothesis Testing (sometimes called Confirmatory Data Analysis) is one of the most important tools of application of statistics to real life problems. It involves conducting tests and experiments to see if a proposed explanation (Statistical Hypothesis) for an observed phenomenon works in practice. Most often, decisions are required to be made concerning populations on the basis of sample information and statistical tests are used in arriving at these decisions.

The methods of Hypothesis Testing differ mainly in what feature of an observed phenomenon is taken as the focus.
