In an experiment, the independent variable is the variable that can be altered or controlled to produce a change. The result being studied is the dependent variable, which is observed to change as the independent variable is changed.
Example : In an experiment testing the effect of caffeine on reaction times, the amount of caffeine consumed is the independent variable and can be varied. The reaction times are the dependent variable, and a correlation (change in times) with the independent (amount given) is the information being sought.
There are three kinds of variables. These are:
Independent variable: is not affected by any effects in the experiment
Dependent variable: its reaction does depend on other variables
Controlled variable: variable that you can control throughout the entire experiment
To put it simply, the independent variable tries to manipulate the dependent variable in an experiment.
The independent variable (manipulated variable) is a variable that is changed by the experimenter. The dependent variable (responding variable) is what you are trying to determine in an experiment. My 6th grade science teacher taught us a poem
The manipulated is what you control the responding variable is your ultimate goal.

What is the diffrence between dependent variable and independent variable?
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
Distinguish between an independent variable and a dependent variable?
The independent variable is the value being manipulated or changed, while the dependent variable is the observed result of the independent variable being manipulated. "IF" you change the independent variable, "THEN" what happens to the dependent variable?
Difference between independent and dependent?
independent variable is the one you control. the dependent variable depends on the indepdendent variable (the results). on the graph independent in on the bottom and dependent is on the side
The relationship between dependent variable and independent variable?
A dependent variable depends on the other factors while an independent variable does not depend on the other factors.
Whats the diffrence between the independent varible and dependent varible?
The independent variable may - or may not - affect the dependent variable. But the dependent doe not affect the independent.
As the independent variable increases the dependent variable does what?
Depends on the relationship between the independent and dependent variables.
What is the diffrence between dependent variable and independent variable?
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
What is the difference between indepedent and dependent variables?
An independent variable is manipulated by the researcher to see its effect on the dependent variable. The dependent variable is what is being measured or observed in the experiment and is influenced by changes in the independent variable. In other words, the independent variable causes a change in the dependent variable.

What is a factor in a experiment that you measure to gather results?
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.
A statement of a possible relationship between the independent and dependent variables?
A dependent variable is a variable dependent on the independent variable. A control variable is something you want to try to keep the same. A dependent variable is something you measure. An independent variable is something you change.
What is the difference between the independent and dependent variables in the experiment?
Dependent variable is your data, independent variable is what you are testing. Ex. Sunlight would be the independent variable and a plants growth would be the dependent variable.
What are the differences between independent and dependent variables?
Independent variables are controlled or manipulated by the researcher to determine their effect on the dependent variable. Dependent variables, on the other hand, are the outcome or response that is measured in an experiment. The independent variable causes a change in the dependent variable.
What the differences between the independent variable and dependent variable?
An independent variable is a variable which stands independent and is unaffected by other variables. A dependent variable is a variable which is a response to the independent variable, and is usually the factor that is being tested in an experiment.
If the independent variable increases what happens to the dependent variable?
It depends on the relationship, if any, between the independent and dependent variables.
What best describes the relationship between a dependent variable and an independent variable in a scientific investigation?
The independent variable is what you are changing in the experiment to get varied results. The dependent variable is the result of what you have changed. So the dependent variable depends on the independent variable. For example, if you are experimenting with the effect of water on height of a plant, the different amounts of water that you give the plant is the independent variable. The height of the plant that you measure as the result of the water is the dependent variable.
