How does confounding variable affect the study?
A confounding variable is a third variable that influences both the independent and dependent variables. Failing to account for confounding variables can cause you to wrongly estimate the relationship between your independent and dependent variables.
Can confounding variables affect an experiment?
In a research study, a confounding variable can change the outcome of an experiment, as an external variable, the third factor can transform both independent and dependent variables in a research and thus affecting outcomes of correlational or experimental research.
How do confounding variables affect validity?
A variable is considered to be confounding because it provides an alternative explanation for your results; that is, an alternative explanation for the relationship or differences between the variables and/or groups that you are measuring. This threatens the internal validity of your results.
What problems can confounding variables cause?
What problems can confounding variables cause? They can cause the study to favor certain results unexpectedly. They can cause incorrect conclusions to be drawn from the study.
Why are confounds a concern in an experimental study?
Why are confounds a concern in an experimental study? They make it unclear what was responsible for a change observed in the dependent variable.
What does it mean when an experiment is confounded?
A confounding variable is an “extra” variable that you didn't account for. They can ruin an experiment and give you useless results. They can suggest there is correlation when in fact there isn't. They can even introduce bias.
What does confounding mean in research?
What is confounding? Confounding is often referred to as a “mixing of effects”1,2 wherein the effects of the exposure under study on a given outcome are mixed in with the effects of an additional factor (or set of factors) resulting in a distortion of the true relationship.
What is a confounding effect?
What is confounding? Confounding is often referred to as a “mixing of effects”1,2 wherein the effects of the exposure under study on a given outcome are mixed in with the effects of an additional factor (or set of factors) resulting in a distortion of the true relationship.
How do you deal with confounding variables?
There are several methods you can use to decrease the impact of confounding variables on your research: restriction, matching, statistical control and randomization. In restriction, you restrict your sample by only including certain subjects that have the same values of potential confounding variables.
What is a confounding variable variable?
Confounding variables are those that affect other variables in a way that produces spurious or distorted associations between two variables. They confound the "true" relationship between two variables.
What is a confounding variable quizlet?
Confounding variable. an extraneous variable whose presence affects the variables being studied so that the results you get do not reflect the actual relationship between the variables under investigation.
What confounding means?
1 : to throw (a person) into confusion or perplexity tactics to confound the enemy. 2a : refute sought to confound his arguments. b : to put to shame : discomfit a performance that confounded the critics. 3 : damn.

Confounding variables are those that affect other variables in a way that produces spurious or distorted associations between two variables. They confound the "true" relationship between two variables.
What is a confound in an experimental study quizlet?
What is a "confound" in an experimental study? an extra variable that could explain result differences between groups.
