Question

variable - something that is changed.
in scientific experiments there are two variables: one that you control and one that is the result.

1. the independent variable

“the cause”
the one thing that is changed in an experiment
this variable makes one test “independent” of another test
on a graph it is on the x - axis (along the bottom)

1. the dependent variable

“the effect”
the result of the experiment
what is measured
this “depends” on what you changed
on a graph, it is on the y - axis (along the vertical side)

Explanation:

In scientific experiments, the independent variable is the cause that is manipulated, and is plotted on the x - axis. The dependent variable is the effect, the measured result that depends on the independent variable, and is on the y - axis.

Answer:

Independent variable: The cause, manipulated variable, on x - axis. Dependent variable: The effect, measured result, on y - axis.
