Fix It
Dr. Arvey is interested in gender stereotypes. She notices the color of a popular social networking website is blue and wonders what might happen if it were also offered in pink. She hypothesizes that when given the choice of colors, men will be more likely to keep their profiles blue and women will be more likely to switch their profiles to pink. She also thinks that being able to choose the default color on the social networking site will increase one's use of the site. To that end, Dr. Arvey puts up flyers around campus asking for volunteers to participate in research, and she ultimately obtains a sample of 90. She wants to conduct the study in her school's computer lab where the participants can access their social media accounts. The computer lab has 30 seats so she asks the volunteers to sign up for one of three sessions. By running 30 participants at a time she believes she is being very efficient in data collection.
