are presented in this section as bar graphs and, in appendix 6.4a, as tables of summary
statistics.
6.4.1 The Beck Self-Concept Inventory for Youth: descriptive statistics
The results in figure 6.4.1 show that nine out of ten students in group A and seven out
of eight students in group B, recorded a drop in their self-concept in the short-term
follow-up data.

Individual students
After a period of no music therapy, most students recorded their self-concept as lower
than before. Table 6.4a.1 in appendix 6.4 shows that there is a similar standard
deviation in the two groups (group A=9.81; group B=8.01). This supports the case
that most students need on-going therapy rather than finishing at twenty weeks
because the results have become worse rather than plateaued.
The students’ follow-up data were compared in their school groups too (figure 6.4b.i
in appendix 6.4b) and it shows that the three students who improved in their scores
were all from The Centre School.
