Question
Read the scenario below, then answer the questions about its design and interpretation.
Researchers at a local hospital want to know whether they really need to have staffed
information booths at all of the hospital entrances or just by the main doors at the front of
the building. The hospital administration wants to make sure that people get the help they
need when they come in, but having employees stationed at multiple centers is very
expensive. To address this question, the researchers decide to do two separate
observational studies. First, they poll everyone entering each doorway to see whether
they are first-time or repeat visitors. They find that 90% of the visitors using doors other
than the main entrance have been to the hospital before. Then they conduct the second
study: They station research assistants in the side/back entrance halls to observe the
behavior of visitors during periods of time when (1) the information booths are fully
staffed, (2) when the booths are unstaffed and a sign is posted that points towards the
main entrance, and (3) when the booths are unstaffed with no sign.
In the first study...
1. What is the independent variable?
a.
2. What is the dependent variable?
3. Which of the following inferences are the researchers most likely trying to examine in the |
first study? (choose best answer and explain)
a. Different locations cause differences in visitor type (repeat/first-time)
b. Differences in visitor type (repeat/first-time) cause differences in which doors
visitors use
c. There is an association between door location and visitor type (repeat/first-time),
and causality does not matter
