Within the Health Data Analytics domain, a dependent variable represents the outcome or effect being studied, which changes in response to variations in one or more independent (causal) variables.

In regression analysis, the dependent variable quantifies the effect being predicted or explained, such as infection rate, readmission rate, or patient satisfaction.

Independent variables are inputs or predictors, such as staffing levels or process compliance.
