In a properly designed experiment how many mainpulated responding and controlled variables should you have why?

In a properly designed experiment, it is important to have at least 2 controlled variables. With two variables you are able to remove one at a time and see the effect in your setup.


Why is a negative control important in an experiment?

A negative control is crucial in an experiment because it helps establish a baseline to compare the effects of the experimental treatment. It ensures that any observed changes in the experimental group are due to the treatment itself and not other factors or random variations. By including a negative control, researchers can confirm that the experimental setup is functioning properly and validate the reliability of their results.


Do all experiments have a control?

All properly-designed experiments should have some sort of control.


Which best explains why replicating an experiment should be done by someone other than the person who original did the experiment?

It shows that the experiment is designed properly.


What primary principal of experimental design did their experiment fail?

The primary principle of experimental design that their experiment likely failed is the control of variables. Without properly controlling for extraneous variables, it becomes challenging to establish a clear cause-and-effect relationship between the independent and dependent variables. This lack of control can lead to confounding factors influencing the results, thereby compromising the validity and reliability of the experiment's findings.
