WebbA scree plot shows a line plot by specifying the variance explained by each factor on the vertical axis and the number of factors on the horizontal axis. The number of factors is determined by inspecting the shape of scree plot where there is an ^elbow _ in the plot. WebbElbow (Scree) plot In the previous exercises you have calculated the total within-cluster sum of squares for values of k ranging from 1 to 10. You can visualize this relationship using a line plot to create what is known as an elbow plot (or scree plot).
