2. You want to use PCA to better understand a dataset that consists of data about different types of trees. (see picture below) Each tree has data on: tree height, trunk width, leaf width, leaf length, width of tree crown, crown height, bole height, points per leaf, some of which are shown in Figure 7 below. Give a brief explanation of how you might use PCA to uncover information about this data set. Figure 7: Some of the measurements taken for each tree
