National Trail Surfaces Study

Treatment of Data

The research design for this study was developed to collect data on trail surface conditions, evaluate individual surface performances over time, note deficiencies, and compare across surface types. Through further analysis, results of trail surface tests for firmness and stability were compared within surface composition categories and across surface composition categories to determine the mean, range and standard deviation of each surface type. Descriptive statistics were used for analysis of data. A one-way analysis of variance (ANOVA) was used to determine if there was any statistical significance between surface composition categories. Sequence charts were run and analyzed for each surface composition category to determine if any patterns, similarities and/or differences between surface compositions could be discerned. Lastly, qualitative data on the surface material conditions during the site visit was collected in order to provide a narrative description of findings.
