A question or measure used to indicate a case's value on a variable is called what?

• A. Concept
• B. Indicator
• C. Open-ended questions
• D. Mutually exclusive

Answer: (B)

The important idea is how we turn an idea into something we can measure for each person. A concept is the abstract notion you want to study, like education level or socioeconomic status. An indicator is the concrete, observable measure used to assign a value to that concept for each case. It’s the specific question or data point that signals where a person falls on the variable. For example, to measure education level, indicators might be years of schooling or highest degree earned—these are observable, comparable signals you collect. Open-ended questions are a data collection method that yields qualitative responses, not a single value for a variable. Mutually exclusive describes categories that can’t overlap, which is a property of coding, not the signal used to indicate a case’s value.
