The term that refers to any variable that can mislead the researcher by affecting the dependent variable is indeed an extraneous variable. Extraneous variables are those that are not intentionally studied but may influence the results of an experiment or a research study. If these variables are not controlled or accounted for, they can create confusion, leading researchers to draw incorrect conclusions about the relationship between the independent and dependent variables.

For instance, if a study is examining the effect of a new therapeutic intervention on clients' emotional well-being, factors like age, socio-economic status, or pre-existing mental health conditions could act as extraneous variables. By not controlling for these influences, the study might incorrectly attribute changes in emotional well-being solely to the intervention when other factors are also at play. Thus, recognizing and managing extraneous variables is crucial for maintaining the integrity and validity of a research study.
