The Cluster Membership is a little bit detailed, so we won't spend much time on it, but obviously this is telling you for each individual case where they ended up, depending on whether or not we put them into three clusters or four clusters or five clusters. Figuring out how many clusters you need is one of the trickiest things that you have to do, and we're going to be getting a lot of practice deciding whether we want a more granular solution, like putting them into eight clusters, or a less granular solution, like putting them into three clusters.
