There are so many factors to take into account and evaluate. The research question , ethics , budget and time are all major considerations in any design. This is before looking at the statistics required, and studying the preferred methods for the individual scientific discipline. Every experimental design must make compromises and generalizations , so the researcher must try to minimize these, whilst remaining realistic.

For biology, psychology and social sciences, there can be a huge variety of methods to choose from, and a researcher will have to justify their choice. The first method is the straightforward experiment, involving the standard practice of manipulating quantitative, independent variables to generate statistically analyzable data. Generally, the system of scientific measurements is interval or ratio based. The researcher is accepting or refuting the null hypothesis. The results generated are analyzable and are used to test hypotheses , with statistics giving a clear and unambiguous picture.

This research method is one of the most difficult, requiring rigorous design and a great deal of expense, especially for larger experiments. The other problem, where real life organisms are used, is that taking something out of its natural environment can seriously affect its behavior. It is also the biggest drain on time and resources, and is often impossible to perform for some fields, because of ethical considerations. The Tuskegee Syphilis Study was a prime example of experimental research that was fixated on results, and failed to take into account moral considerations.

In other fields of study, which do not always have the luxury of definable and quantifiable variables - you need to use different research methods. These should attempt to fit all of the definitions of repeatability or falsifiability , although this is not always feasible. Opinion based research methods generally involve designing an experiment and collecting quantitative data. For this type of research, the measurements are usually arbitrary, following the ordinal or interval type.

Questionnaires are an effective way of quantifying data from a sample group, and testing emotions or preferences. This method is very cheap and easy, where budget is a problem, and gives an element of scale to opinion and emotion. These figures are arbitrary, but at least give a directional method of measuring intensity. Qualitative research presents non-quantitative type of analysis. Qualitative research is collecting, analyzing and interpreting data by observing what people do and say.

Qualitative research refers to the meanings, definitions, characteristics, symbols, metaphors, and description of things. Qualitative research is much more subjective and uses very different methods of collecting information,mainly individual, in-depth interviews and focus groups.

The nature of this type of research is exploratory and open ended. Small number of people are interviewed in depth and or a relatively small number of focus groups are conducted. Qualitative research can be further classified in the following type.

A culture is the shared attributes, values, norms, practices, language, and material things of a group of people. In addition to the above, we also have the descriptive research. Fundamental research, of which this is based on establishing various theories.

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?

In an ideal world, experimental research methods would be used for every type of research, fulfilling all of the requirements of falsifiability and generalization. However, ethics, time and budget are major factors, so any experimental design must make compromises.

A wide range of research methods are used in psychology. These methods vary by the sources of information that are drawn on, how that information is sampled, and the types of instruments that are used in data collection. Methods also vary by whether they . Types of research Experiments People who take part in research involving experiments might be asked to complete various tests to measure their cognitive abilities (e.g. word recall, attention, concentration, reasoning ability etc.) usually verbally, on paper or by computer.

Business research methods can be defined as “a systematic ad scientific procedure of data collection, compilation, analysis, interpretation, and implication pertaining to any business problem”[1]. Types of research methods can be classified into several categories according to the nature and. Research can be classified in many different ways on the basis of the methodology of research, the knowledge it creates, the user group, the research problem it investigates etc. This research is conducted largely for the enhancement of knowledge, and is research which does not have immediate.
