Question

Quizplus · Accepted Answer

A variable is any concept, characteristic or attribute that can take on different values or levels. In research, variables are the concepts that researchers measure, manipulate, and analyze to understand their relationship to the phenomenon under inquiry. Variables are measurable and observable, which means that they can undergo a measurable change during research. For example, in an experiment, the independent variable (the variable that is manipulated) can be manipulated to measure its effect on the dependent variable (the variable that is measured). Thus, option B is the best choice since it explicitly mentions a concept that can undergo a measurable change.
