Precise ways to measure variables in research are referred to as operational definitions, which specifies the procedures used to measure or manipulate the variables being studied. Reliability refers to the consistency of measurements or results, correlation refers to the strength and direction of a relationship between variables, and validity refers to the accuracy of a measurement or whether it is measuring what it is intended to measure. While these concepts are important for research, they do not specifically address the need for precise measurement procedures.
