Choose your x and y carefully.

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

You are watching: Does the dependent variable go on the x axis

This does not typical that the x variable is out partying if the y variable is whining around the x variable never ever being about -- that"s co-dependence, i m sorry is a completely different kettle of fish.

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

Personally, ns still mix increase right and also left, and I find the native "dependent" and "independent" a little confusing. So i think "cause" (the x variable) and "effect" (the y variable). This is not precisely right and will do some researchers apoplectic, however as a type of memory aid, the might help you too. So,

• The cause is how far the child sits from the TV - the x change

• The impact is exactly how much eyesight she loser - the y variable.

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

Sometimes the "x" change can"t actually be controlled yet only "chosen" by researcher -- this is especially the situation when some variation of "time" is the x variable.

However, be careful. Just due to the fact that a variable has time does not mean that it is automatically the x variable. Occasionally the quantity of time a procedure takes is the impact of a treatment, and then that is the "y" variable.
