Concept: ”Alternative hypothesis and Null hypothesis”

Hypothesis is an assumption or explanation made on the basis of limited proof. It serves as an origin point for further examination, experimentation or surveying.

Alternative hypothesis

When a person tries to prove a hypothesis and he/she succeeds in it , then it is called as alternative hypothesis.It confirms the fact that the variables listed under the hypothesis have statistical backing or proof.

Alternative hypothesis summarizes that the researcher’s reasoning is true.

Null hypothesis

When a person who expects to reach an alternative hypothesis finds the hypothesis to be disapproving, it is called as null hypothesis.It rejects the variables listed under the hypothesis and proves that they have no statistical or experimental backing.

Null hypothesis indicates the changes or revisions to be made on the variables chosen for  the study of a hypothesis.Thus the outcome of every testing will either prove alternative hypothesis or null hypothesis as true.
