What is the IV
Michael is the branch manager at
a little-known regional paper
supplier. He wants to see if music
in the break room can make his
employees more productive.
Despite HR objections, he plays a
different genre of music each
week--classical music, rap, rock,
and pop. At the end of the month,
he analyzes the numbers and sees
no significant differences.
