Given below are two statements : One is labeled as Assertion A and the other is labeled as Reason R. Assertion (A) : When Null Hypothesis (H0) is rejected, researcher's hypothesis (H1) is accepted.  Reason (R) : Null Hypothesis (H0) is a chance hypothesis and as such (H1) being true, the researcher's hypothesis lies in the domain of acceptability.  In the light of the above statements, Choose the most appropriate answer from the options given below :  Correct Answer Both (A) and (R) are correct and (R) is the correct explanation of (A).

A hypothesis can be defined as a tentative statement that is a generalization and the validity of which remains to be tested. It is guiding print to research.

Key PointsAssertion (A): When the Null Hypothesis (H0) is rejected, the researcher's hypothesis (H1) is accepted. 

  • The null hypothesis is assumed to be true unless there is strong evidence to the contrary – similar to how a person is assumed to be innocent until proven guilty.
  • A research hypothesis is a specific, testable prediction about what you expect to happen in a study
  • The null hypothesis is the reverse of the Research hypothesis.
  • The researcher’s aim is to refuse this hypothesis on the basis of the obtained results so that it is reversed.

Hence, the assertion is correct.

Reason (R): Null Hypothesis (H0) is a chance hypothesis and as such (H1) being true, the researcher's hypothesis lies in the domain of acceptability. 
  • It is derived from the researcher’s theory about some aspects of behavior known as the research hypothesis.
  • It is also called the Working hypothesis.
  • The null hypothesis is the reverse of the Research hypothesis.
  • Researchers' have the faith and belief that their hypothesis is true as it is derived from the theory which is adequate to answer the research proposition.

Hence, the reason is also correct.

Therefore, both (A) and (R) are correct but (R) is the correct explanation of (A).
