Question

"Identify an extraneous variable the researcher would need to control in this experiment and explain the effect it might have had on the results if it had been left uncontrolled."

Answer 1

Situational variables.

Step-by-step explanation:

Extraneous variables are variables which are not the independent variables but could have an affect in the result of an experiment if left unattended or and uncontrolled. Extraneous variables can be important determiners to provide alternative explanations of an experiment.

Situational variables are those aspects of the environment that might affect the participant’s behavior. These aspects could be in terms of location, noise, temperature, lighting conditions, etc. at the time of the experiment. If they are not controlled or provided the same to all the participants, there can be a difference in the result of the experiment.
