Jan 12, 2018 · This document discusses extraneous variables that need to be controlled in experiments to avoid confounding results. It describes four types of extraneous variables: physical, social, personality, and context variables.
May 1, 2021 · There are five main types of extraneous variables: 1) physical variables related to the testing environment, 2) response style where subjects answer in predictable ways, 3) response set where subjects respond based on social desirability rather than the question, 4) demand characteristics where subjects behave how they think the experimenter ...
Extraneous variables are anything other than the independent variable that could affect the dependent variable. In this study they could include participant differences, environmental variables such as temperature or noise, and experimenter variables including the way in which the research is conducted.
Apr 2, 2021 · In an experiment, an extraneous variable is any variable that you’re not investigating that can potentially affect the outcomes of your research study. If left uncontrolled, extraneous variables can lead to inaccurate conclusions about the relationship between independent and dependent variables.
Mar 25, 2024 · Extraneous variable is a variable that is not the main focus of a study, but which may affect the outcome or results of the study. Extraneous variables can be sources of error in research and can potentially confound the relationships between the variables being studied.
