Question

A history class of 50 students has agreed to be the subject of a research study. Half of the class has been asked to study for the next history test while listening to classical music. The remaining half has been asked to study in a completely silent environment. The test scores of the two groups will be compared at the end of the experiment. In this experiment, which of the following is the dependent variable

Answer 1

Answer:

The options are absent, but the dependent variable in this experimental setup is the test scores from both groups of the experiment.

Step-by-step explanation:

The dependent variable, just like the name suggests, is the variable whose value or outcome depends on the some other variable(s) in an experimental setup.

For this research study, the aim is to evaluate the effect of a silent studying environment or listening to classical music while studying on the academic performance of students as reflected in their test scores.

So, for each of the two groups in this experimental setup, the test scores of the students should depend directly on the the effects of either of the two conditions mentioned earlier. Hence, it is evident that the test scores of students is the undisputed dependent variable for this experimental setup.

Hope this Helps!!!
