Suppose we conduct a study on whether hand stamps at bars affect behavior. As patrons enter a bar, they are randomly assigned to receive one of the following hand stamps:

“AIDS Kills”
“Practice Safe Sex”
Smiley face
No stamp

At the exit of the bar, there is a table where people can buy condoms at a greatly reduced price. We are interested in seeing if the type of hand stamp affects how many condoms patrons buy. It was hypothesized that a fear message (“AIDS Kills”) would be more effective in persuading people to buy condoms than a non-fear message (“Practice Safe Sex”). Both the “AIDS Kills” and “Practice Safe Sex” stamps should be more effective in persuading people to buy condoms than an unrelated stamp (smiley face) or no stamp at all.
