Question

A/An _____ is a type of variable that is not accounted for in a research experiment. independent variable dependent variable confounding variable.

Answer 1

A confounding variable is not accounted for in research experiments.

Explanation: When a confounding variable is present, it has the potential to alter the relationship between the dependent and independent variable. In turn, this can lead to distorted or false experiment findings. For example, if an experiment is being conducted on a sample of students, regarding the relationship between caffeine consumption and its effect on academic performance, a potential confounding variable could be the varying amounts of sleep each participant got prior to the expirement. Adequate sleep could very well affect academic performance. However, this variable cannot be considered because it is not the main subject of the experiment.

Answer 2

Confounding

Step-by-step explanation:

In research, we usually have two different types of variables:

• The independent variable is the one that the researchers can control and that will have an effect on another variable.

• The dependent variable is the one that cannot be control and that is affected by the independent variable. Researchers observe this variable to see how it changes. This is the variable that will be tested or measured.

However, sometimes an unexpected type of variable appear: a confounding variable is an influence (from outside) that changes the relationship or the effects of the other two variables. It is usually a variable that the researcher couldn't control and they affect the validity of the experiments.

Therefore, a confounding is a type of variable that is not accounted for in a research experiment
