These results show that four students (44%) scored their self-concept as lower and
five students (56%) as higher. Therefore, more than half of the students’ scores
improved but there is a uniform and minimal amount of change across all the students
from the lowest to the highest score which suggests that they have not changed very
much. There are two exceptions which are shown at each end of the graph. They are
outliers because their scores are very different to the others: Joe‘s score is extremely
low compared to the others but his circumstances were also quite different to other
students who were referred from CVC and his case study is given in chapter eight;
and Daniel showed significant improvement compared to the others. Due to Daniel’s
difficulties, he had been moved forward into group A (5.3.3) because it was felt that
he needed therapeutic intervention immediately and these statistics reflect the
successful decision to begin his music therapy straightaway (9.3.2).
The summary statistics in table 6.2.3 include the mean increase and mean decrease,
which show these steady changes in CVC students’ scores.
