Comparing Proportions of Different Samples

  • Robert D. Drennan
Part of the Interdisciplinary Contributions to Archaeology book series (IDCA)


Sometimes we have a sample divided into subsamples as in the example in Chapter 12, but the comparison we wish to make between the subsamples concerns not the mean of some measurement but rather another set of categories. Such a comparison can be approached by estimating population proportions from the various subsamples and attaching error ranges to the estimates. Then the estimated population proportions with their error ranges can be compared to each other with a bullet graph just as we did for means in Chapter 12.
