Note. Group LE (lower elementary) = 1 st -2 nd graders; group UE (upper elementary) = 5 th graders;
group MS (middle school) = 6 th -7 th graders; group HS (high school) = 10 th -12 th graders).
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.
