Figures & data
Fig. 1 Left: The activity kit that each group of students receive. Right: An alternative activity kit.
Fig. 2 Demonstration of the first step in agglomerative hierarchical clustering, where point 1 and point 3 were merged together.
Fig. 3 Scatterplot of the dataset.
Fig. 4 Steps of activity based on the single linkage criterion.
Fig. 5 Steps of activity based on the complete linkage criterion.
Fig. 6 Steps of activity based on the group average linkage criterion.
Fig. 7 Illustration of the 2-cluster solutions based on the single linkage (with the chaining effect), the complete linkage (with the crowding effect), and the group average linkage criteria. The last merging rule offers a compromise solution between the previous two criteria.
Fig. 8 The dendrograms produced by R.
