Researchers have found that college student pedestrians are prone to accidents when using their phones in various ways while crossing the street (Byington & Schwebel, 2013; Schwebel et al., 2012; Stavrinos et al., 2011). These studies have used both dependent and independent groups.
1. Suppose you want to examine this topic with adults in your community. You decide to use a repeated measures and expose 24 participants to all four conditions [talking on their cell phone (T), texting on their cell phone (X), listening to music (M), playing a game on their cell phone (G)]. How could you use complete counterbalancing to assign your participants to the order of the cell phone conditions (T, X, M, G)? Provide specifics about the possible orders and assignment to them.
2. Suppose the adults thought the repeated measures study would take too much time and you decided to match the adults on the amount of time (in minutes) they spent daily on their cell phone. Below are the daily cell phone times for the participants. Explain in detail the matching process and assignment to different conditions.
