Statistical Practices of IJPT Researchers: A Review from 1993-2000.

Abstract: Research articles published in the International Journal of Play Therapy (1JPT) were examined to investigate the use of selected statistical practices in quantitative inferential studies. The current article examined whether researchers (a) verified methodological assumptions of statistical analyses, (b) reported confidence intervals, (c) discussed the risk of experimentwise Type I error, (d) preferred univariate analyses to multivariate analyses, (e) used univariate analyses as post hoc methods to detect mult… Show more

“…Results for dependent variables were interpreted using Pillai's trace analysis. To avoid a Type I error resulting from the testing of multiple hypotheses, a .025 alpha level was established to either reject or accept hypotheses (Armstrong & Henson, 2005). To avoid a Type II error than can result from small sample sizes, a power analysis was conducted for each dependent variable and revealed ample power for analysis (≥.80).…”

“…Post hoc paired samples t tests were conducted for both ST and LT groups. To help address the risk of inflated experiment-wise Type I error, the α level used for the post hoc analyses was .025 (Armstrong & Henson, 2005).…”

“…Another limitation to the study was the small sample size which leads to lack of statistical power (Armstrong & Henson, 2005). Due to the ethical responsibility to provide play therapy services to students in need, 11 children who would have been included in the sample size were removed from the sample because they were receiving play therapy services at the time the intervention was conducted.…”
