Quizplus · Accepted Answer

The standardized math test score is the variable being measured and is dependent on whether or not the students were allowed to use calculators. Therefore, it is the dependent variable. The independent variable in this experiment is the use of calculators. A confound is an extraneous variable that can impact the results of the experiment, and a placebo is a substance or treatment that has no therapeutic effect. Neither of these terms apply to the standardized math test score in this experiment.
