What are the three types of variables?
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
How many variables should you have when you start an experiment?
An experiment involves three types of variable.The independent variable is the one you are investigating. It is the one which you deliberately vary in the experiment. You should only have one independent variable.The dependent variable is the variable which you measure to get your results. Often there is only a single dependent variable but there can be more.All other variables must be controlled ie kept constant so they do not change the result. There are usually many control variables in an experiment.

What is the control in an expiriment?
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.
Definitions of the 3 types of variables in doing an experiment?
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.
In an experimental investigation the variable that the researcher changes or manipulates in order to see its effects is called the?
Independent variable, is variable that the experimenter manipulates
Independent and dependentare types of these?
Independent and dependant are types of variables in an experiment. The independent variable is what is being manipulated within the experiment and the dependant variable is the result of that change.
How many variables do you need in a science experiment?
Ideally, an experiment should test only one variable (the independent variable) at a time. If you have two or more variables changing at the same time you have no way of knowing which variable is causing your results.
What are Variables in an experament?
A variable of an experiment is anything that is changed either deliberately, or as a result of changing something else. An independent variable is one that is changed to obtain a different result. A dependent variable is the thing that changes as a result of changing the independent variable. There is also the controlled variable, or just control, which does not change throughout the experiment. A test or a trial
What are Three types of variables?
Control Variable, Independent Variable, Dependent Variable.
What would be the best level of the independent variable to be the control for this experiment?
Measured variable, control variable, treatment variable and moderating variable
What are the four different types of variables?
Measured variable, control variable, treatment variable and moderating variable
