Question

A researcher wants to study the effects of alcohol on cognitive function. The experimental group is given 10 ounces of alcohol, while the control group gets a nonalcoholic beverage. Participants must then complete a 40-question test that requires varying levels of cognitive function. Scores on the test are compared, and it is found that the group that drank alcohol performed worse than the group that drank the nonalcoholic beverage. In this experiment, __________ is the dependent variable.

Answer 1

The dependent variable in the experiment is the test scores on the cognitive function test.

Step-by-step explanation:

In this experiment, the dependent variable is the scores on the cognitive function test completed by participants after consuming either alcohol or a nonalcoholic beverage.

The dependent variable is the outcome that the researchers are measuring, which in this case, is the cognitive performance as assessed by the test scores.

This is what is being affected during the experiment and is dependent on the level of alcohol consumption, which is the independent variable.
