Statistics: The Taste of Water

Australian curriculum number (ACMSP253; ACMSP277; ACMSP278)

Students test a common claim (that bottled water tastes different to tap water) and collect experimental data. They determine the statistical significance of their findings. This sequence introduces students to informally conducting experiments to test hypotheses.

Students should be familiar with ideas associated with variation, randomness and probability and have some facility with the use of spreadsheets.


Lesson 1: The Taste of Water

Students test whether they can taste the difference between tap and bottled water by collecting and interrogating experimental data. This lesson can serve as an introduction to the concept of the p-value as students compare their results to the likelihood of finding the same result by sheer chance.
