What are manipulating and responding variables?
The manipulating variable is the independent variable and the researcher controls and changes it during the experiment. The responding variable is the dependent variable and changes during the experiment, when the researcher alters the manipulating variable.
If doubling the manipulating variable results in a doubling of the responding variable the relationship between the variables is a?
Controlling Variables are the variables that stay the same. The Manipulated Variable is the variable that you changed on purpose. There can only be one manipulated variable. The Responding Variable is the variable that was changed due to the experiment. For example, if you were testing how fast ice melts with differet materials, the responding variable would be the time it took for the ice to melt. Again, there can only be one responding variable.
The responding variable is the one variable that changes as a result of altering the manipulating variables. In an experiment, different conditions of the responding variable can be observed, such as quantity, quality, time, distance and height.

A dependent (responding) variable is a condition that can change as the result of an independent variable's alteration. It can also be referred to as an effect. Every well-designed experiment has three kinds of variables. 1) Control variables, which are the same for each stage of the experiment. 2) Independent (manipulated) variables, which represent what is being changed by experimenters. 3) Dependent (responding) variables, which respond to the change and ideally are the direct result…
