For the purpose of this book, research is defined as thedeliberate study of other people for the purposes of in-creasing understanding and/or adding to knowledge. Thisdeliberate study could cover many different areas. As a re-searcher, you might be interested in attitudes and beha-viour – why do people think in a certain way and whydo they behave in a certain way? Or you might be inter-ested in numbers – how many people use a service? Per-haps you need to try to predict how this number ofpeople could be increased so that you can obtain fundingfor your service. Or you might be fascinated by the perso-nal history of a neighbour and have a burning desire torecord her history and pass it on to others.
