Marcus investigated the effect of background music style on reading comprehension. He used an opportunity sampling technique to recruit 24 participants. Marcus allocated his participants randomly to one of two conditions. Condition A: participants read a 500-word article for 5 minutes while listening to background pop music with lyrics. Condition B: participants read the same 500-word article for 5 minutes while listening to background instrumental classical music without lyrics. Marcus recorded the participants' scores on a 10-item comprehension questionnaire completed immediately after reading.
