10 lis 2023 · Extraneous variables are factors other than the independent and dependent variables that may unintentionally influence the results of an experiment. They need to be controlled, minimized, or accounted for through careful experimental design and statistical analysis to avoid confounding the relationship between the independent and dependent ...
2 kwi 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.

5 gru 2023 · Extraneous variables can create spurious relationships between stimulus variables and response variables and are variables that need to be controlled. For example, age as an extraneous variable will confuse the relationship between annual income and cancer probability.
In this chapter, we will deal with three very important concepts: systematic variance (also called between group variance), systematic error (also called confounding), and random error (also called within-group variance or error variance).
3 sty 2024 · Extraneous Variables: Additional variables that are not intentionally observed or manipulated. Extraneous variables may inadvertently affect the dependent variable. We don’t want this as it interferes with the internal validity of the study!
