Question

Mozart Will listening to a Mozart piano sonata make
you smarter? In a 1995 study published in the journal
Psychological Science, Rauscher, Shaw, and Ky reported
that when students were given a spatial reasoning section
of a standard IQ test, those who listened to Mozart for
10 minutes improved their scores more than those who
simply sat quietly.

a) These researchers said the differences were statisti-
cally significant. Explain what that means in context.

b) Steele, Bass, and Crook tried to replicate the original
study. In their study, also published in Psychological
Science (1999), the subjects were 125 college students
who participated in the experiment for course credit.
Subjects first took the test. Then they were assigned
to one of three groups: listening to a Mozart piano
sonata, listening to music by Philip Glass, and sitting

for 10 minutes in silence. Three days after the treat-
ments, they were retested. Draw a diagram displaying

the design of this experiment.
c) These boxplots show the differences in score before
and after treatment for the three groups. Did the
Mozart group show improvement?d) Do you think the results prove that listening to Mozart
is beneficial? Explain.
