Cluster Sampling to Identify Risk
Ned Jones, Owner and Statistician, 1-alpha Solutions
Sample units do not always lend themselves to being sampled one at a time but rather must be sampled in clusters. The need to sample clusters maybe the result of logistics, economics or convenience or any combination of these factors. In this situation identifying the risks presented by the commodity or other item requires a cluster sampling approach. Sampling clusters to detect risk can be confusing but the JMP Profiler provides a clear way forward and an easily understood picture.
