Quizplus · Accepted Answer

The statement about BMI > the 95th percentile representing overweight is an operational definition, as it provides a specific and measurable criterion for categorizing individuals as overweight. It is not a conceptual definition because it is not defining the abstract concept of overweight, but rather providing a concrete identification method. It is also not a dependent or independent variable as it is not being manipulated in the study or used as an outcome measure.
