Describing atypical individuals may lead to poor generalizations and detract from external validity. In survey method research, participants answer questions administered through interviews or questionnaires.

After participants answer the questions, researchers describe the responses given. In order for the survey to be both reliable and valid it is important that the questions are constructed properly. Questions should be written so they are clear and easy to comprehend. Another consideration when designing questions is whether to include open-ended, closed-ended, partially open-ended, or rating-scale questions for a detailed discussion refer to Jackson, Advantages and disadvantages can be found with each type:.

Open-ended questions allow for a greater variety of responses from participants but are difficult to analyze statistically because the data must be coded or reduced in some manner. Closed-ended questions are easy to analyze statistically, but they seriously limit the responses that participants can give. In addition to the methods listed above some individuals also include qualitative as a distinct method and archival methods when discussing descriptive research methods.

It is important to emphasize that descriptive research methods can only describe a set of observations or the data collected. It cannot draw conclusions from that data about which way the relationship goes — Does A cause B, or does B cause A? Nothing could be further from the truth.

By Jamie Hale, M. Observational Method With the observational method sometimes referred to as field observation animal and human behavior is closely observed. Ecological validity refers to the extent to which research can be used in real-life situations. Case Study Method Case study research involves an in-depth study of an individual or group of indviduals. Survey Method In survey method research, participants answer questions administered through interviews or questionnaires.

Consequently, it can be helpful for the researchers to have some kind of additional record of the interview such as an audio or video recording. They should of course obtain permission before recording an interview. Case studies usually involve the detailed study of a particular case a person or small group. Various methods of data collection and analysis are used but this typically includes observation and interviews and may involve consulting other people and personal or public records.

The researchers may be interested in a particular phenomenon e. Case studies have a very narrow focus which results in detailed descriptive data which is unique to the case s studied. Nevertheless, it can be useful in clinical settings and may even challenge existing theories and practices in other domains.

Studies which involve observing people can be divided into two main categories, namely participant observation and non-participant observation. In participant observation studies, the researcher becomes or is already part of the group to be observed.

This involves fitting in, gaining the trust of members of the group and at the same time remaining sufficiently detached as to be able to carry out the observation. The observations made might be based on what people do, the explanations they give for what they do, the roles they have, relationships amongst them and features of the situation in which they find themselves. In non-participant observation studies, the researcher is not part of the group being studied.

The researcher decides in advance precisely what kind of behaviour is relevant to the study and can be realistically and ethically observed. 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?

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 .

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.
