The test was split with 70% for the training set and 30% for the test set. 9 clusters were conducted and the results are shown the plot 1. The plot suggest 2,4 , 5 and 6 solutions might be interpreted.

The second plot shows the canonical discriminant analyses of the 4 cluster solutions. Clusters 0 and 3 are very densely packed together with relatively low within-cluster variance whereas clusters 1 and 2 were spread out more than the other clusters, especially cluster 1 which means there is higher variance within the cluster. The number of clusters we would need to use is less the 3.

Students in cluster 2 had higher GPA values with an SD of 0.70 and cluster 1 had lower GPA values with an SD of 0.79
