Sampling Summary

Figure 1. Stage summary
Stage Summary from Complex Samples Sampling Wizard.

This summary table reviews the first stage of sampling and is useful for checking that the sampling went according to plan. Recall that you requested a 30% sample of townships by county; the actual proportions sampled are close to 30%, except in the Western and Southern counties. This is because these counties each have only six townships, and you also specified that a minimum of three townships should be selected per county.

This summary table (the top part of which is shown here) reviews the second stage of sampling. It is also useful for checking that the sampling went according to plan. Approximately 20% of the voters were sampled from each neighborhood from each township sampled in the first stage, as requested.
