What is a factor called when it can affect the result but is neither deliberately changed nor controlled in an experiment?

Answer and explanation

Correct answer: Extraneous variable

An extraneous variable is a factor that may influence the result but is not the main variable being tested. If the researcher neither changes it deliberately nor keeps it constant, its effect can become mixed with the effect of the independent variable. This can introduce unwanted variation and make it difficult to decide what really caused the observed result. Good experimental design tries to identify and control such factors where possible.

Option A is correct because it defines an uncontrolled factor that can affect the outcome. A dependent variable is the measured result, while a constant is a condition deliberately kept the same. A control group is a comparison group, not a factor. For example, if temperature is tested but light differs between samples, light may act as an extraneous variable. Therefore, A is the appropriate term.
