Defining your variables and deciding how you will manipulate and measure them is an important part of experimental design. A doctor changes the dose of a particular medicine to see how it affects the blood pressure of a patient.

Difference between dependent and independent variables for one independent variable there may be more than one dependent variable. It s easy to get these mixed up but the difference between dependent and independent variables is simple.

Mostly in mathematical equations dependent variables are denoted by y. The independent and dependent variables are the two key variables in a science experiment. Dependent variables are also termed as measured variable the responding variable or the explained variable.
