This term is usually used for functions. Suppose a function f is defined in a domain D and has values in a set S. then, the elements of D are usually called independent variables. This name comes from the fact that yiu can change it's values independently.
For example, consider the function f defined in R by f(x) = x^2. We usually write y = x^2. Here x is the independent variable and y is the dependent one. Because you can choose values for x and y depends on x.

An independent variable is 1 that does not depend on any other variable for it's value, as opposed to a dependent variable that does. Mathematically, we can generally rearrange equations to make any variable independent & any variable dependent.
Phusically, this is not always the case. For example in the equation:
V=V0+at, t is is the independent variable & V is the dependent variable. We can rearange this to:
t=(V-Vo)/a so that V is independent & t is dependent. Mathematically, this is valis & sometimes usefull. Physically, t is always independent, as there is nothing we can do to change time.

1. variable determining value of others: the variable in a mathematical statement whose value, when specified, determines the value of another variable or other variables
2. variable manipulated in an experiment: a variable that is manipulated in an experiment in order to observe the effect on another variable

Say your conducting some scientific analysis on an experiment. You have a dependent variable as well as an Independent variable. By manipulation Two hypnosis = one conclusion

If you have a quarter and a nickel they equal 30 cents and a penny is in your pocket. You put the penny into the laundry in your pants pocket - then the quarter and the nickle still equal 30 cents. The penny is kind of floating around in the wash water but it has nothing to do with the quarter and the nickle so it is the independent variable: it will not change the total when you add the quarter to the nickel.
