Question

Quizplus · Accepted Answer

Confounding can occur in any experimental design, not just those with small sample sizes, a single independent variable, or in factorial experiments. It refers to a situation where the effect of the independent variable on the dependent variable is mixed up with the effect of another variable, making it difficult to determine the true cause of any observed changes.
