Two researchers tell you they study the same thing. However, when you look at their research papers, they do not use similar methodologies or measurements. How is this possible? The researchers have the same conceptual definitions (constructs) and operational definitions The researchers do not have the same conceptual definitions (constructs) nor the same operational definitions The researchers have the same operational definitions The researchers have the same conceptual definitions (constructs)
The researchers have the same conceptual definitions (constructs)
Which of the following is true of operational definitions? Conceptual definitions are created after operational definitions are determined. Operational definitions and conceptual definitions are the same thing. There is only one operational definition that is possible for each conceptual definition. The specification of operational definitions is one of the creative aspects of the research process.
The specification of operational definitions is one of the creative aspects of the research process.

There will be greater construct validity
