Assume that you are the nurse at a large elementary school where children frequently come to you with nosebleeds. Design an experiment to test whether dropping keys down the back of the neck causes nosebleeds to stop. (Assume parents of all children in the school have given permission for their participation in the experiment and you have followed ethical guidelines for research with human subjects. One possible explanation for why keys down the back might actually be effective in stopping a nosebleed is that they are cold, causing blood vessels to constrict. Treatments should be randomly assigned to the children. Describe how you accomplish this. That is, when a child with a nosebleed comes to the nurse's office, how will you know which treatment he or she should get?
