Students’ Understanding of Variation on Entering Tertiary Education
Researchers use statistics to make judgements about their data. Did the new drug work better than the old drug? What is the best combination of feed, temperature and water conditions for breeding abalone in an artificial environment? What methods of teaching fractions work? In all these situations, researchers only have access to a part of the population, a sample. It is not possible to examine all the people who will ever take a drug to see how it works, nor is it possible to test all the students who are learning about fractions.
