Choose your x and also y carefully.

Scientists choose to say that the "independent" variable goes ~ above the x-axis (the bottom, horizontal one) and the "dependent" variable goes top top the y-axis (the left side, upright one).

You are watching: What variable goes on the x axis

This go not median that the x change is the end partying while the y variable is whining around the x variable never ever being about -- that"s co-dependence, i m sorry is a totally different kettle the fish.

When you"re talking about variables, "independent" way that the researcher (you, or someone else in a white coat) deserve to pick any kind of value he/she desires for the variable. Using the TV viewing distance data, you have the right to imagine the researcher putting little pieces of tape on the floor and also positioning her little experimental topics at just the right distance ... Whereas i can"t think of any method the researcher deserve to directly control how much eyesight the children lost.

Personally, i still mix up right and left, and I uncover the native "dependent" and "independent" a small confusing. So i think "cause" (the x variable) and also "effect" (the y variable). This is not precisely right and will make some scientists apoplectic, however as a sort of memory aid, it might help you too. So,

• The cause is how far the son sits native the TV - the x change

• The effect is just how much eyesight she loser - the y variable.

OK, now you try: because that each pair, what is "x" and also which is "y"?
