Jerrika wants to study the impact of caffeine consumption on performance in a classroom. She takes two classes (one meets at 9 a.m. and the other meets at 3 p.m.) and provides caffeine to the 9 a.m. class. She then compares scores on identical exams between the two classes. She finds that caffeine dramatically affects performance by improving scores. What might be a concern about the conclusions she draws about her data?
◦ Assignment to the experimental versus control groups was not random.
◦ There may have been a placebo effect.
◦ The conclusions would be stronger if she had varied the exams between the two classes as well.
◦ Jerrika cannot compare scores on identical exams.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
