Dr. Dоrmeur studies sleep аnd sleep disоrders. She is curiоus аs to whether technology exposure before bedtime cаuses people to fall asleep more slowly. She recruits a sample of 60 middle-aged women from a local church who reported no history of sleep problems. She creates three conditions. All participants come to the sleep lab for three nights in a row and experience all three conditions. In the first condition (A), participants are asked to play an online game (Candy Crush) on an iPad for 10 minutes prior to going to bed. In the second condition (B), participants are asked to use an iPad to read an article that discusses tricks and tips for improving one’s score on Candy Crush (which takes about 10 minutes). In the third condition (C), participants are asked to read a newspaper article about the inventor of Candy Crush (which takes about 10 minutes). With the use of an electroencephalograph (EEG), the researcher measures how long it takes participants to fall asleep. Given that there are three conditions/levels of the independent variable, how many orders of the conditions are possible in Dr. Dormeur’s study?
