An Independent Variable is the factor that is directly controlled or change. OR the part that you change.
A Dependent Variable is the part measured or what you are looking for in the experiment.
A constant is what never changes.
A Sample Size is the # of subjects tested or observed.
You're WELCOME!!!
I literally JUST learned this in school today!
The independent variable may - or may not - affect the dependent variable. But the dependent doe not affect the independent.
for responding varible the same thing is a dependent varible for manipulated varible the same thing is independent varible
the dependent variable cant change the independent varible, but the independent variable can change the dependent varible. (eg: Bob wants to see if the new baseball pitching machine throws better fastballs then his friend. The baseball pitching machine(independent) could change a fastball(dependent), but a fastball(dependent) cant change the baseball pitching machine(independent).
The dependent variable ( responding variable ) is the variable that changes on purpose.
Independent varible is what the person changed.Dependent varible is what is the same.
An independent variable is one which does not rely on another variable for its value. For example, in the slope intercept form: y = 2x + 3 The x is the independent variable and the y is the dependent variable. The x can be set to anything, therefore it is independent. The value of y is dependent on x for its value.

the dependent varible
An Independent Varible Means : Something that you don't change in your experiment.
Controlled
the dependent variable cant change the independent varible, but the independent variable can change the dependent varible. (eg: Bob wants to see if the new Baseball pitching machine throws better fastballs then his friend. The baseball pitching machine(independent) could change a fastball(dependent), but a fastball(dependent) cant change the baseball pitching machine(independent).
Variables used in an experiment or modelling can be divided into three types: "dependent variable", "independent variable", or other.The "dependent variable" represents the output or effect, or is tested to see if it is the effect.The "independent variables" represent the inputs or causes, or are tested to see if they are the cause. Other variables may also be observed for various reasons.
