To study the effectiveness of possible treatments for insomnia, a sleep researcher conducted a study in which four participants were instructed to count sheep (the Sheep Condition), four were told to concentrate on their breathing (the Breathing Condition), and four were not given any special instructions (the Control Condition). The average number of minutes taken for participants to fall asleep over the next seven days were:

    Sheep condition: 39, 33, 42, 38

    Breathing condition: 33, 25, 31, 27

    Control condition:  44, 41, 38, 41
