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
What are variables that the scientist changes in an experiment?
Scientists change the independent variable but measure the dependent variable; other variables are kept constant.
What are the independent dependent and control variables?
The independent variable is the thing you are changing/varying. The dependent variable is the thing you are measuring. This variable should be affected by the independent variable. Control variables are anything that must be kept constant. If there are any other factors which affect the dependent variable, then these need to be controlled so that they do not have any significant effect (basically ensuring that you are actually measuring the effects of the independent variable).
What does independent variable and dependent variable mean?
The independent variable is the variable that the scientist controls and can change in an experiment. There should be only one independent variable in an experiment; otherwise the cause-and-effect of the independent variable cannot be determined.The dependent variable is the variable that is affected by the independent variable.EXAMPLE:Students of the same age have been given different sleeping hours (the independent variable)The next day they are tested for their performance (the dependent variable).(Having students the same age is a third type of variable, called the constant variable or the control variable. It is deliberately kept the same to reduce any effects on the outcome.)
Why is it important to have a constant in an experiment?
In order for the results to be valid, the dependent variable can only be affected by the independent variable, so somethings need to be kept CONSTANT. The things that need to be kept constant are called CONTROLLED VARIABLES. Even if controlled variables are affecting the dependent variable(s), which they usually do, keeping them constant will ensure that all trials of an investigation were equally impacted by the controlled variables, therefore allowing one to see the impact of an independent variable on the dependent variable. All in all, a 'constant' in a science experiment should actually be called a 'controlled variable' and the description of such a variable is described in the third point. Hope this clarifies.
What does dependent mean in science?
You may be asking about dependent variables, as in a lab activity. There are also independent variables. The independent variable is the thing that is controlled or kept monitored by the scientist. The dependent variable is what occurs or changes as a result of the independent variable.

What is mmeant by a controlled expirment?
Instead of changing something, independent variable, where it is likely to change the dependent variable, the control is kept the same.
What are variables that the scientist changes in an experiment?
Scientists change the independent variable but measure the dependent variable; other variables are kept constant.
What is the factor of interest in an experiment called?
The independent variable. Any variable that is kept the same is a constant variable (although it is a contradiction in terms); any variable - usually only one - that depends on the independent variable is a dependent variable.
What are the independent dependent and control variables?
The independent variable is the thing you are changing/varying. The dependent variable is the thing you are measuring. This variable should be affected by the independent variable. Control variables are anything that must be kept constant. If there are any other factors which affect the dependent variable, then these need to be controlled so that they do not have any significant effect (basically ensuring that you are actually measuring the effects of the independent variable).
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.
What are the scientific variables and what do they mean?
In an experiment, the independent variable is the variable that is manipulated, for example plant fertilizer. The dependent variable is what is observed and measured as a result of the independent variable, for example plant height. Controlled variables are factors that are kept constant for the entire experiment, such as temperature and moisture, so that the observed results are due only to the independent variable. So in an experiment measuring the effect of fertilizer on plant growth, the independent variable would be the fertilizer, the independent variable would be the height measured at specific intervals, and the controlled variable of temperature and moisture would be kept the same for both groups.
What is another name for dependent variable?
the 'y' variable
