2.1 Which units to use

It is important to choose appropriate units, both to have a sense of the size you are talking about and also to avoid having to deal with very large or very small numbers.

For example using the UK decimal system, where £1 = 100p (one pound is equivalent to 100 pence), you would probably use pence for prices less than a pound: 50p rather than £0.50 and pounds for larger amounts, e.g. £2.50 instead of 250p.

For distance, mass and liquid measures, the metric system of units

1.4.1 Discourse involves work

If discourse is doing something rather than doing nothing, what kinds of things are being done? We can see that Diana's account in Extract 1, like all accounts, constructs a version of social reality. When we talk we have open to us multiple possibilities for characterizing ourselves and events. Indeed, there are many ways Diana could have answered Bashir's first question in the extract above. Any one description competes with a range of alternatives and indeed some of these alternativ

7.2 Averages

The mean, median and mode are all types of average and are typical of the data they represent. Each has advantages and disadvantages, and can be used in different situations, but they all give us an idea of the general size of the values involved. Here we provide brief definitions, and some idea of when each should be used.

2.2.11 Scandals, treatments and cost saving

In the 1960s critics of the quality of care for older people, such as Peter Townsend, The Last Refuge (1962), and Barbara Robb, Sans Everything (1967), added their voices to growing criticisms of institutional care, not only for older people but for users of mental health services and people with learning difficulties too. Government had already begun to take account of its responsibilities for the dire state and cost of many of these institutions and in a famous speech in 1961

3.1 What makes a nation, a state or a nation-state?

Why do England, Scotland and Wales take part in the Six Nations rugby championship alongside Italy, Ireland and France? Are they all ‘nations’? What do we mean by calling them ‘nations’? The nation has become one of the most contested concepts of our times. Scholars, politicians and political activists present different definitions of the nation, usually focusing on a variety of cultural, political, psychological, territorial, ethnic and sociological principles.
