Comparisons with Descriptive Data

Chapter Chapter 11 in Better Business Decisions from Data, 2014, pp 103-113 from Springer

Abstract: Abstract Chapter 6 explained that descriptive data can be rendered numerical by expressing the numbers of items in various categories as proportions—thus enabling further analysis to be carried out on the data. In this chapter, a single proportion will be compared with a population, and two sample proportions will be compared. If the data is ordinal—that is to say, it can be listed in logical order—then ranking tests, which will be introduced, can be applied to achieve comparisons between pairs of ranks.
