Question

current attempt in progress
stimuli other than independent variables that may affect the outcome of the study and lead to erroneous conclusions are called
o confounding variables.
o placebos.
o random variables.
o external variables.

Explanation:

• Confounding variables are factors other than the independent variable that can influence the outcome of a study and lead to incorrect conclusions.
• Placebos are inert substances used in experiments, not variables affecting outcomes.
• Random variables are variables with unknown values, not specifically about affecting study outcomes wrongly.
• External variables is a more general term, but the specific term for this situation is confounding variables.

Answer:

confounding variables.
