| Summary: | Circular statistics are used to analyse directional data inherent in X-ray densitometric data that pertain to cross-sectional discs sampled from balsam fir wave forest trees at Spirity Cove, Newfoundland. The analysis concentrates on directionality of centroids of mean wood density, bole eccentricity, and tree-ring width in eight directions from the pith. The results show that the centroid of mean wood density, bole cross sections, and mean tree-ring width are significantly directional and correspond closely with the mean vector wind direction. |
