Music Preference 65
Note. Treatment N = no introduction to musical selections; treatment ID = musical selections
introduced through discussion. Music preference ratings were given on a five-point Likert scale,
from 1 (Very Unenjoyable) to 5 (Very Enjoyable). Due to rounding, numbers in the Difference
in M (ID-N) column appear to vary slightly from differences as calculated from the means as
reported to two significant digits in the Treatment N and Treatment ID columns.
a Percentage is based on the difference in means in proportion to the maximum possible
difference in ratings.
