Ans: C
The dependent variable is the outcome or result that the investigator is studying. The dependent variable can change (e.g., health status, knowledge, behavior). Characteristics or phenomena and the health conditions being studied are the variables. Control groups and comparison groups are essential to ensure that associations between variables can be examined. The presumed "cause" of or contributor to variation in the dependent variable is the independent variable.
