What 3 types of variables are there in a controlled experiment. Define all three for the points. Also, why do you need to only have one independent variable?
Independent variable: The one variable in the experiment that is being tested or changed to see if it really is the “Cause”,.Dependent Variable: The result or outcome of an experiment - We are trying to run an experiment to see if the cause is making the desired effect happen. Constant Variables: All of the factors that have to be kept the same in order to make it a fair test.You need an independent variable to determine whether or not it is the cause of the dependent variable.
What is a controlled experiment?
An experiment with a comparison of 2 groups in which only one variable is manipulated at a time: The independent variable AKA the suspected “Cause” is being manipulated/changed.
What is the definition of operational?
An agreed upon way of measuring variables and or of performing certain tasks during a controlled experiment.
