6 Minute Walk Test configuration and method of measurement comparisons and reliability

Data comparing three different course configurations and two different methods of measurements. For methods of measurements, a paired t-test was used to analyze differences. For the configurations, a repeated measures ANOVA was used to analyze differences, and post hoc tests with Bonferroni correction used to locate the sources of difference. Config A represents a 12-meter straight walkway, Config B represents a 30-meter straight walkway, and Config C represents a 12-meter by 1.2-meter rectangular walkway. For reliability, interclass correlation coefficient using a two-way random model and absolute agreement to determine inter- and intra-rater reliability.

本数据集针对三种不同的步道配置与两种测量方案展开对比分析。针对测量方案，采用配对t检验（paired t-test）分析组间差异；针对步道配置，采用重复测量方差分析（repeated measures ANOVA）分析差异显著性，并通过实施Bonferroni校正的事后检验（post hoc tests）定位差异产生的具体来源。其中，配置A为12米直行走道，配置B为30米直行走道，配置C为12米×1.2米的矩形行走道。在信度检验环节，采用基于双向随机模型（two-way random model）与绝对一致性判定准则的组内相关系数（interclass correlation coefficient），对评定者间信度与评定者内部信度进行评定。
