thanksWhat is a control of an extraneous variable?
What you just asked is a contradiction- an extraneous variable is something you can't control but may influence the outcome of a study.What is a control of an extraneous variable?
An extraneous variable is a variable that is not being measured in an experiment but may influence the results. For example, if you want to measure the effect of room temperature on concentration, noise coming in through the windows may influence your results and is therefore and extraneous variable. A control would be to soundproof the room. In other words, a control of an extraneous variable is something that eliminates the influence of that variable on the test results.
