Introduction
As part of your quality of measurement coursework you will be required to devise an approach to an experiment and then carry it out and perform some careful data analysis of your results.

There are many ways to tackle a problem (some better than others) as the following story illustrates:

The following is a question on a physics exam at the University of Copenhagen: "Describe how to determine the height of a skyscraper with a barometer."

One student replied: "You tie a long piece of string to the neck of the barometer, then lower the barometer from the roof of the skyscraper to the ground. The length of the string plus the length of the barometer will equal the height of the building." This highly original answer so incensed the examiner that he failed the student who immediately appealed on the grounds that his answer was indisputably correct. The university appointed an independent...
