In a research study with multiple measured outcomes, which is the dependent variable?

Explanation:
The main idea is that the dependent variable is what you measure to assess the effect of the independent variable, and in a study with multiple outcomes, the data are collected for each participant. When several outcomes are recorded, the patient serves as the unit of analysis—the entity across which all outcomes are observed and compared. The other options describe specific outcomes or measurements, not the broad entity being studied across all outcomes. So, the patients themselves are the dependent variable because the study tracks multiple outcomes for each patient.
