l - The results of a survey of ve individuals on a two item survey are presented below. Person X1 X2 a 2 4 b 8 2 c 9 3 d 1 5 e 8.5 l a Draw the scatter diagram for these observations and indicate if you believe that the observations may form clusters. b The following table shows the distances between the observations. Use these distances to show how you would use the agglomerative clustering method to reduce the number of clusters from 5 to 1. Develop both a table showing the step-by-step clustering of observations, and a diagram showing the same process.
