Stage summary
This summary table reviews the rst 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 specied that a minimum of
three townships should be selected per county.
