Water Taste Test Data

Abstract

In this paper we present data collected from two water taste tests conducted at Longwood University in the fall of 2008. These data are appropriate for performing exploratory data analyses and inference using the test for a single proportion and chi-square tests, including the goodness-of-fit test and the test for independence. The data also provide opportunities for students to consider the cell-count assumptions for chi-square tests, as some tests meet the assumptions and others do not. Finally, the results from the taste tests raise questions about sustainability issues related to consumer preference, bottled water consumption, and its environmental impacts.
