Extraneousvariables exist in all experiments, and the researchers frequentlystruggle to control or even avoid these variables if possible. Thesevariables have the latent to affect the results of an experimentsubstantially if they are not controlled. Due to the impact that theextraneous variables can have on the results, researchers attempt toavoid or control these variables in their research. Typically thereare four types of extraneous variables, and they include: situationalvariables that entail the nature of the environment around the placeof the research and they can be controlled. The person variables arethose that describe the interaction of the researcher with theexperiment, and they can also be avoided such as anxiety and moods.The experimenter effect is where the researcher makes an assumptionof what the final results are supposed to be while leaning on hispoint of view. Therefore, researchers are expected to strive toensure that both these variables have little impact on their results.
