    So for a hot or cold room, you would need to say what actually defines a hot or cold room. So your IV would be something along the lines of 25 C or 15 C. For the DV you need to be able to define what exercising well actually means. Is it how long they can run on a treadmill for or how many press ups that can do? How many calories burnt? Based on a survey or physical check on how they feel after the exercise? For example, the DV could be the amount of press ups completed correctly in a certain time limit.

    1. The researcher wants to make sure that it is the manipulation of the independent variablethat has changed the changes in the dependent variable. Hence, all the other variables that could affect the DV to change must be controlled. These other variables are called extraneous or confounding variables.
