Consider only the following variables: the importance attached to enjoying nature, relating to the weather, and living in harmony with the environment, exercising regularly, and meeting other people (V2 to V6).
a. Cluster the respondents based on the identified variables using hierarchical clustering. Use Ward's method and squared Euclidean distances. How many clusters do you recommend and why?
b. Cluster the respondents based on the identified variables using the following hierarchical methods: (a) single linkage (nearest neighbor), (b) complete linkage (farthest neighbor), and (c) method of centroid.
c. Cluster the respondents based on the identified variables using A-means clustering and the number of clusters identified in (a). Compare the results to those obtained in (a).
