Vanessa is planning on conducting a study that looks into how listening to music impacts learning. Specifically, she wants to know how well people can learn while listening to their favorite, or least favorite, type of music. For her study, she has all participants study a list of words (for 20 minutes) while listening to music. Half of the participants study the list while listening to their favorite music.
