Working with Aggregate Data: An Excel Macro for Pairwise Comparison Using Z Test for Two ProportionsDOI: 10.4236/oalib.1103927, PP. 1-9 Subject Areas: Statistics, Education, Mathematical Statistics, Sociology, Politics Keywords: Pairwise Comparison, Two-Proportion Z-Test, Aggregated Data, Internet Data, Excel VBA Macro Abstract
A Visual Basic for Applications (VBA) Excel macro
was created for doing a pairwise, two-sample Z-test of within-column proportions fork data rows in an Excel spreadsheet. By program iteration, the Z-score for k(k－1)/2 unique,
non-repeating and non-duplicated within-column comparisons was generated and the null hypothesis is tested against a
two-tailed Z-score critical value.
This within-column process is useful for extracting potential meaning from
large aggregate columnar data. The procedure
was demonstrated using aggregate internet acquired summary data in the
public domain. The VBA macro is provided and it is also available at the
author’s website.
