The observation can be carried out in a few different ways. For example, it could be continuous over a set period of time e. Observation does not only include noting what happened or was said but also the fact that a specific behaviour did not occur at the time of observation. Observational trials study health issues in large groups of people but in natural settings. Longitudinal approaches examine the behaviour of a group of people over a fairly lengthy period of time e.

In some cases, the researchers might monitor people when they are middle-aged and then again after 15 years and so on. The aim of such studies is usually to determine whether there is a link between one factor and another e. The group of people involved in this kind of study is known as a cohort and they share a certain characteristic or experience within a defined period. Within the cohort, there may be subgroups e.

In some cases, rather than following a group of people from a specific point in time onwards, the researchers take a retrospective approach, working backwards as it were.

They might ask participants to tell them about their past behaviour, diet or lifestyle e. This is not always a reliable method and may be problematic as some people may forget, exaggerate or idealise their behaviour. For this reason, a prospective study is generally preferred if feasible although a retrospective pilot study preceding a prospective study may be helpful in focusing the study question and clarifying the hypothesis and feasibility of the latter Hess, The Delphi method was developed in the United States in the s and s in the military domain.

It has been considered particularly useful in helping researchers determine the range of opinions which exist on a particular subject, in investigating issues of policy or clinical relevance and in trying to come to a consensus on controversial issues. The objectives can be roughly divided into those which aim to measure diversity and those which aim to reach consensus. There is no limit to the number of panellists involved but between 10 and 50 might be considered manageable.

The panellists are chosen on the basis of their expertise which could take many forms e. Is Alzheimer's disease hereditary? Is there a test that can predict Alzheimer's disease?

Even the production of numbers is guided by the kinds of questions asked of the subjects, so is essentially subjective, although it appears less so than qualitative research data. This is carried out when we wish to understand meanings, look at, describe and understand experience, ideas, beliefs and values, intangibles such as these.

This is a common approach and helps you to 'triangulate' ie to back up one set of findings from one method of data collection underpinned by one methodology, with another very different method underpinned by another methodology - for example, you might give out a questionnaire normally quantitative to gather statistical data about responses, and then back this up and research in more depth by interviewing normally qualitative selected members of your questionnaire sample.

Look at the very brief outlines of different methods below. Consider which you intend using and whether you could also find it more useful to combine the quantitative with the qualitative.

Interviews enable face to face discussion with human subjects. If you decide to interview you will need to draw up an interview schedule of questions which can be either closed or open questions, or a mixture of these. Closed questions tend to be used for asking for and receiving answers about fixed facts such as name, numbers, and so on. They do not require speculation and they tend to produce short answers.

With closed questions you could even give your interviewees a small selection of possible answers from which to choose. If you do this you will be able to manage the data and quantify the responses quite easily. The Household Survey and Census ask closed questions, and often market researchers who stop you in the street do too.

The problem with closed questions is that they limit the response the interviewee can give and do not enable them to think deeply or test their real feelings or values. This would give you a very good idea of the variety of ideas and feelings people have, it would enable them to think and talk for longer and so show their feelings and views more fully.

But it is very difficult to quantify these results. You will find that you will need to read all the comments through and to categorise them after you have received them, or merely report them in their diversity and make general statements, or pick out particular comments if they seem to fit your purpose.
