Popular legend has it that the full moon brings out the worst in people. The full moon has been
linked to crime, suicide, mental illness, disasters, accidents, fertility, and even werewolves. Do you
believe that the full moon influences human behavior? The influence of the moon on human
behavior has been called "The Lunar Effect."
The most widely believed myth about the full moon is that it causes strange behavior. A social scientist
conducted a study to determine if a particular behavior will indeed occur more often during the full moon. Two
weeks before the full moon in April, 15 couples residing in Luna Condominium were randomly selected and
asked to observe if they were engaged in a conflict on that day. They were also monitored through CCTV to
verify their reported behavior. On the day of the full moon, another random sample of 15 couples residing in the
adjacent condominium building were also asked to observe if they were engaged in a conflict. Their reports
were also verified through CCTV.
Consider di = Xday – Xtwoweeks where Xday is the number of couples who were engaged in a conflict on the day of
the full moon and Xtwoweeks is the number of couples who were engaged in a conflict two weeks before the full
moon.
