Quizplus · Accepted Answer

Confounding variables are problematic for researchers because they are variables that vary along with the independent variable, making it difficult to determine if any changes in the dependent variable are actually due to the independent variable or the confounding variable. In other words, confounding variables can mask or distort the true relationship between the independent and dependent variables. Additionally, confounding variables can be difficult to control for, measure, or eliminate from a study design.
