Given below are two statements: one is labeled as Assertion A and the other is labeled as Reason R

Assertion (A): Though ex-post facto research examines cause and effect but it is not part of experimental research.

Reasons (R): In ex-post facto research, effect of independent variable has already taken place.

In the light of the above statements, choose the most appropriate answer from the options given below

Key Points

• Two other forms of quantitative research, which are not experimental due to lack of manipulation, are ex post facto (sometimes called causal-comparative) and correlational.
• Often, both types are grouped into what researchers call non-experimental or simply correlational research.

So that the Assertion is true.

• Ex post facto research will examine the cause-and-effect relationship between an independent and dependent variable.
• It will also hypothesize how the independent variable, which is not controlled or manipulated, influences or affects the dependent variable.
• Neither test score is thought to cause the other, so there is no independent variable to manipulate.
• In fact, the terms independent variable and dependent variable do not apply to this kind of research.

Hence the reason is also true.

Thus the answer is Both (A) and (R) are correct but R is the correct explanation of (A)
