Charts, graphs and tables are all very helpful ways of representing a set of data. However, they are not the only ways of passing on information about data. This section looks at how you can analyse a set of data to summarise the given information as briefly and simply as possible.

Essentially, there are two features of a set of data that enable summarising: the average and the spread. This section starts by looking at what is meant by â€˜averageâ€™. If you have already studied OpenL

1.6 Sources of authority

A very useful way of gaining insight into a religion and seeing how it works is to examine its sources of authority: for example, whether authority is vested in scriptures, in religious specialists, in tradition, in personal experience or a combination of these. Even in traditions where there is some agreement on what counts as an authoritative text, there are still contested issues of how that text is to be interpreted, by whom, with what degree of literalness and in what context. Similarly,

6.3 Damping

In the real world, most oscillations are subject to damping and so the amplitude of the oscillation dies away over time. For example, the bell mentioned earlier would not be very effective if it did not lose some of its energy as sound waves. The oscillating cantilever of the AFM will, like the simple mass-spring system, be subject to frictional forces from the air, the material of the cantilever itself, and the fixing point.

For the mass-spring system the damping force Fd

3.3.6 Summary of the system of precedent

The basis of the system of precedent is the principle of stare decisis and this requires a later court to use the same reasoning as an earlier court where the two cases raise the same legal issues. For example:

• House of Lordsâ€™ decisions are binding on all other courts in the legal system, except the House of Lords itself.

• The Court of Appeal is bound by previous decisions of the House of Lords. The Court of Appeal generally is a

5.13.3 Circular plate

By now you shouldn't be at all surprised to learn that when a circular plate that has an outer rim that is free to vibrate is struck, the plate will vibrate in a number of modes at the same time.

The first four modes of vibration of a circular plate with a free edge are shown in Figure 21. As with

3.3 Division

Division is probably the most awkward of the four arithmetic operations. Since you may have a calculator, you do not need to be able to carry out complicated divisions by hand, but you do need to carry out simple divisions in order to check your calculator calculations. Division is the reverse process of multiplication. The quantity 12 Ã· 3 tells us how many times 3 goes into 12. Since 4 Ã— 3 = 12, 12 Ã· 3 = 4.
