Study of association between two variables come under :

  • A.Co-relational design
  • B.Factorial design
  • C.Both (A) and (B)
  • D.Experimental design

Answer: A

The study of association between two variables comes under co-relational design.

A correlational design measures two or more variables as they occur and calculates how strongly they are related, for example between flexibility and hurdling performance, using a correlation coefficient. It shows association but not cause and effect.

A factorial design is an experimental design that tests the effects of two or more manipulated factors, and an experimental design establishes cause and effect, so 'Both' and the experimental option are wrong.
