Measured variable, control variable, treatment variable and moderating variable
I'm thirteen so don't be embarrassed if i know it and you don't. ( no offense) The three types of variables in scientific inquiry is Independent variable Dependent variable Control variable
Fair testing is when you test something with many variables, but you must change one variable. e.g. testing the different types ofdrinking water. [Tap water, hose water, etc.
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
The control is the subject in an experiment not introduced to the dependent variable. For instance if you were to test the effect of different types of fertilizer on plants, the control would be the plant with no fertilizer.
Control Variable, Independent Variable, Dependent Variable.

Ideally you control all variables except for the variable of interest.
The independan variable, the variable that you change I change I ndependant The control variable, the variable that stays the same The Dependant variable, the thing that you measure
The three types of variables are: Independent: it is the one that you manipulate Dependent: the one that reacts to the changes in the independent variable and is measured in a experiment Control: all the other factors that could affect the dependent variable but are kept constant through out an experiment
motor can be control by using variable frequency drive

stupid question
Fair testing is when you test something with many variables, but you must change one variable. e.g. testing the different types ofdrinking water. [Tap water, hose water, etc.
the controlle variable would be the measuring cup because you dont change that
