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. By definition, this experiment method must be used where emotions or behaviors are measured, as there is no other way of defining the variables. Whilst not as robust as experimental research , the methods can be replicated and the results falsified.
Observational research is a group of different research methods where researchers try to observe a phenomenon without interfering too much. Observational research methods, such as the case study , are probably the furthest removed from the established scientific method. Observational research tends to use nominal or ordinal scales of measurement. Observational research often has no clearly defined research problem , and questions may arise during the course of the study.
Observation is heavily used in social sciences, behavioral studies and anthropology, as a way of studying a group without affecting their behavior. Whilst the experiment cannot be replicated or falsified , it still offers unique insights, and will advance human knowledge. Case studies are often used as a pre-cursor to more rigorous methods, and avoid the problem of the experiment environment affecting the behavior of an organism.
Observational research methods are useful when ethics are a problem. 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. As long as a researcher recognizes and evaluates flaws in the design when choosing from different research methods, any of the scientific research methods are valid contributors to scientific knowledge.

Whether you are an academic novice, or you simply want to brush up your skills, this book will take your academic writing skills to the next level.
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. If you decide to use interviews:. Questionnaires often seem a logical and easy option as a way of collecting information from people.
They are actually rather difficult to design and because of the frequency of their use in all contexts in the modern world, the response rate is nearly always going to be a problem low unless you have ways of making people complete them and hand them in on the spot and this of course limits your sample, how long the questionnaire can be and the kinds of questions asked.
As with interviews, you can decide to use closed or open questions, and can also offer respondents multiple choice questions from which to choose the statement which most nearly describes their response to a statement or item.
Their layout is an art form in itself because in poorly laid out questionnaires respondents tend, for example, to repeat their ticking of boxes in the same pattern.
If given a choice of response on a scale , they will usually opt for the middle point, and often tend to miss out subsections to questions.
You need to take expert advice in setting up a questionnaire, ensure that all the information about the respondents which you need is included and filled in, and ensure that you actually get them returned. Expecting people to pay to return postal questionnaires is sheer folly, and drawing up a really lengthy questionnaire will also inhibit response rates. You will need to ensure that questions are clear, and that you have reliable ways of collecting and managing the data.
Setting up a questionnaire that can be read by an optical mark reader is an excellent idea if you wish to collect large numbers of responses and analyse them statistically rather than reading each questionnaire and entering data manually.
You would find it useful to consult the range of full and excellent research books available. These will deal in much greater depth with the reasons for, processes of holding, and processes of analysing data from the variety of research methods available to you. Home Research methods Choosing appropriate research methodologies Choosing appropriate research methodologies Choosing qualitative or quantitative research methodologies Your research will dictate the kinds of research methodologies you use to underpin your work and methods you use in order to collect data.
Types of research methods can be classified into several categories according to the nature and purpose of the study and other attributes. In methodology chapter of your dissertation, you are expected to specify and discuss the type of your research according to the following classifications.
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.
Observational research methods, such as the case study, are probably the furthest removed from the established scientific method. This type is looked down upon, by many scientists, as ‘quasi-experimental’ research, although this is usually an unfair criticism. Observational research tends to use nominal or ordinal scales of measurement. Before beginning any research project, you must decide which methodology to use. This will guide your study, help you to choose a way to collect data and aid in your analysis. Researchers use three primary methodology types: qualitative, quantitative and mixed methods.
Types of Research Methods Adapted from Edvantia SBR Rating for Technical Assistance Programs and Services form () and Carter McNamara Overview of Methods to Collect Information handout. A research method is a systematic plan for conducting research. Sociologists draw on a variety of both qualitative and quantitative research methods, including experiments, survey research.
