Correlational Research basically puts its primary focus on quantifying the relationship between two or more variables but there is no perfect comparision between them but on the other hand Differential Research puts a direct comparison of two or more pre-existing groups of subjects and so as we know low constraint research can serve as a starting point for high-constraint questions and research methods, so, correlation research has a lower level of constraint than differential research.

1. Correlational Research basically puts its primary focus on quantifying the relationship between
two or more variables but there is no perfect comparision between them but on the other hand
Differential Research puts a direct comparison of two or more pre-existing groups of subjects
and so as we know low constraint research can serve as a starting point for high-constraint
questions and research methods, so, correlation research has a lower level of constraint than
differential research.
Solution
Correlational Research basically puts its primary focus on quantifying the relationship between
two or more variables but there is no perfect comparision between them but on the other hand
Differential Research puts a direct comparison of two or more pre-existing groups of subjects
and so as we know low constraint research can serve as a starting point for high-constraint
questions and research methods, so, correlation research has a lower level of constraint than
differential research.
