Lab 2 - BIOL 2050.csv

The study was conducted on September 21, 2016 in a woodlot at York University, Keele Campus, Toronto, ON, Canada by Pham Ha Phuong Do and Victor Suay Espi. For data set #3, a random tree was selected, and 10 pairs of tree were randomly picked from the chosen tree. The distance between the trees in each pair was measured in meter by big measuring tape, and the diameters of each tree picked to pair with the chosen tree was measured in centimeter by a smaller pocket measuring tape. To measure the distance between the trees, the measuring tape was used straight from the edge of the one tree to another. The diameter of the trees was measured at approximately chest height of the main trunks. *Note: Data set #4 and meta data are included in the same sheet, as cvs file doesn't allow multiple sheets in one file.本研究由Pham Ha Phuong Do与Victor Suay Espi于2016年9月21日在加拿大多伦多市约克大学基尔校区的林地中开展。 针对数据集#3，研究人员随机选取一棵选定树木，并随机选取10棵树木分别与该选定树木配对，共形成10组树木配对。每对树木间的间距以米为单位，使用大型卷尺进行测量；而与选定树木配对的每棵树木的直径，则以厘米为单位，通过小型便携卷尺完成测量。 测量树木间距时，需将卷尺拉直，从一棵树的树干边缘直接延伸至另一棵树的树干边缘。 树木直径的测量位置定于主干约胸高（即人类胸部平均高度）处。 *注：数据集#4与元数据均收纳于同一工作表中，因CSV（Comma-Separated Values）格式文件不支持单个文件内包含多个工作表。
