A professor wants to determine whether her students perform better on mid-term examinations if they write their exam alone or in a group.To experimentally investigate this possibility,she randomly assigns half of her students to write their mid-term in the regular class setting (as a group)and randomly assigns the other half of her students to write their mid-term individually in private cubicles in the university's testing centre.Which of the following is a potential confound for this study?
A)The students assigned to the control or experimental groups
B)The mid-term exam scores
C)Memory cues linked to the classroom setting
D)The amount of time required to write the exam

Memory cues linked to the classroom setting could potentially be a confound in this study because students who write the exam in the classroom setting may recall more information due to the association with the classroom context, whereas students in the testing center may not have the same contextual cues to aid their recall. This could potentially affect their exam performance and interfere with the results of the study. The other choices (A, B, D) are not potential confounds in this study.
