Step-by-step explanation:
The question I would like to answer is: Does exposure to music during studying affect how well students retain information?
The independent variable in this experiment is the exposure to music during studying. This variable can be operationally defined as the amount of time students are exposed to music while studying. This can be further broken down into three levels, such as no music, background music, and music with lyrics. This can be measured by having the participants listen to music for a certain amount of time while studying.
The dependent variable in this experiment is the amount of information retained by the students. This can be operationally defined as the scores the students receive on a test designed to measure how much information they remember from the material they studied. This can be measured by having the participants take a test before and after studying with the different types of music. The scores can then be compared to see if there is a difference in how much information they retained.
