Question

Quizplus · Accepted Answer

Controlling for unwanted variability in age, gender, ethnic background, and socioeconomic status helps to avoid or minimize the influence of extraneous or confounding variables, which are factors that could potentially influence the outcome variable and obscure the effects of the independent variable being studied. Dependent variables are the outcomes or measures that are being studied, demand characteristics refer to cues or clues in the experiment that may influence participants' behavior, and practice effects are improvements in performance that may occur simply as a result of repeated exposure to a task.
