C)control variables
D)disturbance variables

Question

Quizplus · Accepted Answer

Unexplained variance or error variance reflects the influence of disturbance variables, which are unmeasured or unknown factors that can affect the outcome of a study. These variables can cause random variability or error in the results, making it difficult to attribute any observed effects solely to the treatment or independent variable of interest. Confounding variables may also contribute to error variance if they are not accounted for in the study design or statistical analysis. Control variables, on the other hand, are variables that are held constant or systematically varied in order to isolate the effect of the independent variable. Treatment effects refer to the effect of the independent variable on the dependent variable, which is typically the focus of the study.
