Understanding the Answer
Let's break down why this is correct
Answer
Operationalizing a variable means defining it in a way that allows it to be measured or tested in research. For example, if a researcher wants to study "happiness," they need to decide how to measure it, like using a survey with specific questions about feelings and experiences. This step is important because it turns a broad idea into something concrete that can be studied. By clearly defining what happiness means in their study, the researcher can collect data that accurately reflects the concept they are interested in. So, operationalizing helps ensure that everyone understands what is being measured and allows for consistent results.
Detailed Explanation
All the options show how to turn ideas into measurable things. Other options are incorrect because Defining income as total salary before taxes is just one way to think about income; Using a questionnaire for happiness is a method, but it doesn't explain how to measure happiness in different ways.
