Detailed explanation-2: -In analytical health research there are generally two types of variables. Independent variables are what we expect will influence dependent variables. A Dependent variable is what happens as a result of the independent variable.

Detailed explanation-3: -An independent variable is identified but not manipulated by the experimenter, and effects of the independent variable on the dependent variable are measured.

Detailed explanation-4: -The second fundamental feature of an experiment is that the researcher controls, or minimizes the variability in, variables other than the independent and dependent variable. These other variables are called extraneous variables .
