1.1.1 Introduction

The data sets you will meet in this section are very different from each other, both in structure and character. By the time you reach the end of the unit, you will have carried out a preliminary investigation of each, identified important questions about them and made a good deal of progress with some of the answers. As you work through the course developing statistical expertise, several of these data sets will be revisited and different questions addressed.

There are seven data sets

6.2 Inverse proportion

The second type of proportional relationship is known as inverse proportion.

Suppose you have decided to hire a taxi to take a group of colleagues from work to the railway station. If the taxi firm charges a set fee for the journey, then the more people who go in the taxi, the less each person has to pay: if two people go, each pays half the cost; if three people go, each pays a third of the cost and if four people go, each person pays a quarter of the cost.

3.4 Maths in business

One of the advantages of identifying the general features of a calculation and then describing it mathematically is that the formula can then be used in either a computer or a calculator program to work out many different calculations quickly and efficiently. Many utility suppliers (gas, water, electricity, telephone) have tariffs based on a fixed daily (or monthly or quarterly) charge and a further charge based on how much you have used during the billing period.

For example in 2005, a

Introduction

This unit is an adapted extract from the course Pure mathematics (M208)

The idea of vectors and conics may be new to you. In this unit we look at some of the ways that we represent points, lines and planes in mathematics.

7.4 Elixirs of the nervous system: neurotrophins

According to Section 7.2 axons obtain an elixir from targets at their synapses.

Confirmation that there is indeed an elixir came from a series of events that reveals how much of science really works. Elmer Bucker, working with Hamburger in the mid-1940s, had removed a limb bud from a chick and replaced it with a tumour from

2.1 Zero electrical resistance

In this section we shall discuss some of the most important electrical properties of superconductors, with discussion of magnetic properties to follow in the next section.

The most obvious characteristic of a superconductor is the complete disappearance of its electrical resistance below a temperature that is known as its critical temperature. Experiments have been carried out to attempt to detect whether there is any small residual resistance in the superconducting state. A sensitive t

3.3 Care: a contested word

You have seen that the words used to label people who are seen as needing care can stigmatise them. By picking them out as unlike ‘normal’ people, people who do not need care, they can feel belittled, de-humanised and deprived of respect. But it is not just the labels like ‘mentally handicapped’, ‘lunatic’ or ‘mentally ill’ that are at issue. ‘Care’ as a word is itself under attack:

Stage 1: The problem situation unstructured

The approach begins with a situation in which one or more people perceive that there is a problem. It will not be possible to define the problem or its setting with any precision and, in any event, the different people involved will have different ideas.

6 Phylogeny and cladistic analysis

In Section 3.3 the point was made that many physiologists consider that desert birds are successful because of their avian physiology, not because of any specific adaptations. While Williams and Tieleman's research on hoopoe larks demonstrated that desert species are capable of flexibility in metabolic rate and evaporative water loss, it suggested that adaptation is important too. The selective advantages of lowered BMR and TEWL for desert birds include reduced energy demand, and lower produc

2.3 Photographs as artefacts

Bear in mind that photographs are artefacts. This means that they are more than just images. The photographer, the process and the packaging all add something to our understanding of the role of the photograph. So, for example, the mount can indicate its purpose (exhibition wall, domestic display, album and so on) and the significance attached to the article in its time. The physical properties of a mount, such as the quality of the card or style of printing, can distinguish top-of-the-range
