A research study on the effects of loud noise on memory. In this study half of his participants studied words in a quiet room and the other half studied in a room with a relatively loud conversation played over loudspeakers. The DR is also interested in knowing if noise will have an effect on difficult versus easy items, so he has all participants study a list of half easy to remember items and half difficult to remember items. Which of the following best describes his design?
