Detailed explanation-1: -A manipulated variable, also known as an independent variable, is a part of an experiment that you can change to see how other variables respond. Here are the three types of variables in an experiment: Manipulated variable: The variable that you control and change based on the experiment.
Detailed explanation-2: -The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect.
Detailed explanation-3: -The independent variable is the variable that is deliberately changed by the scientist. The dependent variable is the one observed during the experiment. The dependent variable is the data we collect during the experiment.
Detailed explanation-4: -Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable.
