Question

10) Below is a Principal Component Analysis (PCA) plot for the Bray-Curtis (1-BCij) data presented in the matrix that is shown on page 5. However, two points are missing (i.e. one open circle for sample 2 and one closed square for sample 6). Draw these two points in the graph where you expect them to appear approximately, based on the Bray-Curtis data and your answers to the 1-BCij portion of question 9 (there is no calculation involved here, just logic). Describe your reasoning: sample 1 0.2 0.15 sample 5 O fungicide applied 0.1 no fungicide 0.05 PC2 0 sample 4 -0.05 -0.1 sample 3 -0.15 -0.2 -0.5 0 0.5 PC1

Step 1

The Bray-Curtis similarity is a statistic used to quantify the compositional dissimilarity between two different sites or samples based on counts at each site. The Bray-Curtis dissimilarity (1-BCij) ranges from 0 to 1, where 0 indicates two samples are identical, Show more…
