Competence was the second reason that our participants involved themselves
in sports and physical activity. After noting that this result slightly contradicts
previous research on perceived motor competence for students with visual
impairments (Brian et al., 2018a) and that sports camps for youth with visual
impairments can increase perceived motor competence (Brian et al., 2018b), we
further analyzed the quantitative data to compare the groups of participants who
had previously attended camp to those who had not. Of the 32 athletes who chose
to identify themselves on their surveys, 46.9% (15 athletes) were returning, while
53.1% (17 athletes) had never attended the same camp or other similar camps in
the past. Once again, it was determined that the residuals were too heavily skewed
(skewness = -1.12), so a Box-Cox transformation (λ=2) was performed and
randomized block ANOVA was run on the transformed data, reducing the
skewness to a more acceptable level (-0.64) with a sample size of n = 360. A
Tukey HSD analysis was performed on the transformed data, creating pairwise
confidence intervals for the differences in the means, with an overall error rate of
.05. The only significant difference in this situation was found between the
transformed means for a) interest/enjoyment versus fitness (t = 2.82, p < .0264).
All other pairwise comparisons had p-values of .33 or higher. Table 6 displays the
results of this analysis.
