Summary Introduction

To review:

The reason behind the proposal of the null hypothesis in addition to research hypothesis while designing an experiment.

Introduction:

Whenever an experiment is proposed, a hypothesis is given which states the possible outcome of that experiment. The hypothesis is then proved correct or incorrect by conducting experiments. On the other hand, a null hypothesis states that there is no statistical difference between the two measured variables in an experiment. It is denoted by $H_0$. Researchers always try to disprove or reject the null hypothesis.
