What is the measurable effect, outcome, or response in which researchers are interested in a study?

• A. Dependent Variable
• B. Independent Variable
• C. Control Variable
• D. Hypothesis

Answer: (A)

The measurable outcome researchers are interested in is the dependent variable. This is the result you observe and quantify to see how it changes in response to the factor you manipulate. In an experiment, you deliberately change the independent variable to test its effect, and you measure the dependent variable to capture that effect. For example, if you study how study time affects test scores, study time is the independent variable and test scores are the dependent variable because they’re the data you collect to assess the impact. Control variables are kept constant to prevent other factors from influencing the outcome, and the hypothesis is the predicted relationship between variables. So the end value you measure—the outcome of interest—is the dependent variable.
