What is the role of the responding variable in a controlled experiment?


please help meWhat is the role of the responding variable in a controlled experiment?
The responding variable is the variable that will change as a result of the change in the manipulated variable. Let look at its role using a hypothetical example. Assume that you are trying to test whether a certain pill will lower blood pressure. Your measurement of blood pressure before and after the treatment is your responding variable. Your controlled experiment is as follows:


1. Sign up a group of people who agree to be studied.


2. Randomly assign people into a treatment and a control group.


3. Measure the subjects blood pressure.


4. Administer a placebo (sugar pill) to the control group and your experimental pill to the treatment group.


5. Measure the subjects blood pressure.


6. Perform a statistical test that examines whether the responding variable (blood pressure measurement) for the treatment group decreased by more than the responding variable of the control group.
