the variable that is most difficult to test
the test variable is the independent variable.
Another name for the test variable is the "independent variable." This variable is manipulated or controlled in an experiment to observe its effects on other variables, typically the dependent variable. In some contexts, it may also be referred to as the predictor variable.
The control is what you're washing, amount of dirt, kind of dirt, temperature of water. The kind and amount of soap are variables, although when using the same kind in different amounts, the kind is control. The temperature of water is also control and variable depending on the test.
The type of variable that responds to the dependent variable is called the independent variable.
