Instructions: As an end of semester treat, NO math involved in this one! For each of the studies list below, first indicate the (A) null and (B) alternative hypotheses. Where possible, note whether it is directional or non-directional. Second, note the (C) IVs and (D) DVs (if present). Third, indicate (E) the most appropriate statistical test to use (Figure 13.1 in Salkind, page 235 may help unless it is a correlational study!). Finally, based on your own thought about how the data would turn out if you ran it, I want you to (F) write up the results as you would see it in an APA results section of an empirical article (make up the statistics, including F values, t values, correlation values, degrees of freedom, means, SDs, etc.. Make sure to write them in APA format and make sure they make sense in context – e.g. if you note significance, it must be higher than the tabled critical values).
1) A researcher is interested in studying whether a company’s sick day policies can influence how much employees feel motivated to work hard. They randomly assign company A to adopt a sick day policy in which employees are given at total of 15 sick days that they may use at any point during the year without question or documentation required, and Company B to adopt a policy in which they are given up to 15 sick days, but they must provide a doctor’s documentation of their illness in order to be able to take the day off. The researcher believes that employees at company A, with the more lenient “no questions asked” policy will feel more motivated to work hard than those at company B, with the stricter sick day policy.
