Station 2
A researcher is studying the effect of
sleep on aggression, thinking that less
sleep will lead to more aggression. She
has some people sleep 6 hours per night,
some people sleep 3 hours per night and
some people sleep as much as they want.
She then monitors aggressive behavior
during basketball games among
participants.

independent variable
Independent variable - the variable that you change in the
experiment
Control Group -

Station 6
A researcher is curious to find out what effect
classical music has on people’s level of relaxation
(as measured by heart rate). He suspects that
listening to classical music will make people feel
more calm and relaxed. He lets one group listen
to classical music for one hour. He lets another
group sit in a quiet room for one hour (i.e they
hear no music). After one hour, he monitors the
heart rate of each participant to measure their
level of relaxation.
