Independent, it is in the name, more variables are:
dependant variable- the one you keep the same
control variable- mearsuring variable
The independent variable. The independent variable. the control.
The independent variable is the variable that you cause to vary during an experiment.
The variable that is deliberately changed is called the independent variable.
Independent Variable
i
the control.constantif you make no changes, then its not called an experiment...The control is variable
The Variable is the one factor that differs in a controlled experiment.
the experimental variable, also called the independent variable
A manipulated variable is also called an independent variable. It is the thing in an experiment you change or manipulate. For example, if i am doing an experiment to see how water affects the growth on plants, the amount of water is the manipulated variable.
A controlled experiment is one in which only one variable is changed at a time. A variable is something which can vary, or have different values. Scientific investigations always involve three types of variables: 1) The independent variable: this is the variable which you deliberately alter, so you will know its values before you start the experiment. For example, if you want to know how the amount of light a plant gets affects its growth, you must give aome plants different amounts of light. Since you need to choose the amounts, you will know the values of this variable before you start the experiment. 2) The dependentvariable:this is the variable you must measure to find out if it changes as a result of you changing the independent variable. Since you have to measure it to find out its values, you will not know the values (ie the results) before doing the experiment. In the plant example you wouls have to find some way of measuring plant growth in the different light conditions. 3) Controlvariables: these are any other variables which may affect the values of your dependent variable, so they need to be kept constant to make it a fair test. In our example, things like the temperature or the amount of water could also alter plant growth, so they would have to be kept constant. These variables are also called confounding variables. The basic principle is only alter one variable (the independent variable) at a time; keep everything else the same.

The variable.
independent variable
Independent variable. The dependent variable is the one that is affected by the independent variable, for example-y=2x+2This is the equation of a line. X is deliberately changed to find y hence - y is the dependent variable and x is the independent variable.
The variable is an experiment that is manipulated by the scientist. APEX
the anwer is a variable( the thng that will change over time in the experiment
The independent variable.
The independent variable.
for Apex: the variable is an experiment that is manipulated by the scientist.
The independent variable is the variable that is changed during an experiment.
The dependent variable is the variable that can change in an experiment.
The Independent variable is the variable being manipulated or changedThe dependent Variable is the observed result of the changed independent variable
Controlling for a variable is the act of deliberately varying the experimental conditions in order to take a single variable into account in the prediction of the outcome variable. Controlling tends to reduce the experimental error. A control is something that does not change in the experiment.
