Independent Variable - Answer The experimental factor that is manipulated; the variable whose effect is being studied. Placed on the x-axis (horizontal) on a graph. Dependent Variable - Answer The variable that is measured in an experiment. Placed on the y-axis (vertical) on a graph. Scientific theory - Answer Must be repeatable. Possible to be disproved and capable of change. Sampling and Sample Size - Answer Random sampling is the preferred, but isn't always possible. A large sample ...
