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.

the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent 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?
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
A dependent variable depends on the other factors while an independent variable does not depend on the other factors.
The independent variable may - or may not - affect the dependent variable. But the dependent doe not affect the independent.
