Find an example of use of a) cluster analysis and b) classification in research or business literature. Preferably, those example should be taken from the same domain. Analyze the problems that were solved with those two methods and the conclusions that were made.

In your initial post summarize both of the cases and highlight why each those methods were selected for each of the examples. Discuss the particular algorithms selection if it is provided. Draw a more general conclusion how to decide which method to use in the similar cases.

Submit at least two responses to other students, where you propose a research question for one of the students' examples using alternative method. For example, if student A provided an example of cluster analysis for a problem P1, reply to her by suggesting a research question that classification would answer within the domain of the problem P1. Do the same for the other example (submitted by students B) where she illustrates the use of classification for problem P2 by submitting an alternative research question that would use cluster analysis for this domain. Finally, you should have 2 examples from the literature (one for each method) in your initial post and two alternative research questions to someone else's examples in your responses.
