Question
Students were involved in an experiment to investogate wheter playing music while they took a test affected their scores .What would their test scores be?a.Interdependent variableb.Controlled variablec.Dependent variabled.Independent variable
Solution
The test scores in this experiment would be the Dependent Variable. Here's why:
a. Interdependent variable: This is not a standard term in experimental design.
b. Controlled variable: These are variables that are kept constant throughout the experiment. In this case, it could be the duration of the test, the difficulty level of the questions, etc.
c. Dependent variable: This is the variable that is measured in the experiment. In this case, it's the students' test scores. The scores depend on whether or not music was played during the test.
d. Independent variable: This is the variable that is manipulated or changed in an experiment. In this case, it's the condition of playing music while taking the test.
