What is K-means in SPSS cluster analysis?
SPSS offers three methods for the cluster analysis: K-Means Cluster, Hierarchical Cluster, and Two-Step Cluster. K-means cluster is a method to quickly cluster large data sets. The researcher define the number of clusters in advance. This is useful to test different models with a different assumed number of clusters.How do you analyze K-means clustering results?
Interpret the key results for Cluster K-Means
1Step 1: Examine the final groupings. Examine the final groupings to see whether the clusters in the final partition make intuitive sense, based on the initial partition you specified. 2Step 2: Assess the variability within each cluster.- k-means is less computationally demanding than hierarchical clustering techniques. The method is therefore generally preferred for sample sizes above 500, and particularly for big data applications.
