Types of research

❶Choosing Appropriate Research Methodologies and Methods - The following website discusses qualitative and quantitative research methods and factors that should be considered when choosing the appropriate method. In most cases, random samples are preferred so that each potential participant has an equal chance of participating but sometimes researchers might want to ensure that they include a certain number of people with specific characteristics and this would not be possible using random sampling methods.

What Are Methods of Studying Human Behavior?

Qualitative research is the approach usually associated with the social constructivist paradigm which emphasises the socially constructed nature of reality. It is about recording, analysing and attempting to uncover the deeper meaning and significance of human behaviour and experience, including contradictory beliefs, behaviours and emotions.

The approach adopted by qualitative researchers tends to be inductive which means that they develop a theory or look for a pattern of meaning on the basis of the data that they have collected. This involves a move from the specific to the general and is sometimes called a bottom-up approach. However, most research projects also involve a certain degree of deductive reasoning see section on quantitative research for more details. Qualitative researchers do not base their research on pre-determined hypotheses.

Nevertheless, they clearly identify a problem or topic that they want to explore and may be guided by a theoretical lens - a kind of overarching theory which provides a framework for their investigation. The approach to data collection and analysis is methodical but allows for greater flexibility than in quantitative research. Data is collected in textual form on the basis of observation and interaction with the participants e.

It is not converted into numerical form and is not statistically analysed. Data collection may be carried out in several stages rather than once and for all. The researchers may even adapt the process mid-way, deciding to address additional issues or dropping questions which are not appropriate on the basis of what they learn during the process.

In some cases, the researchers will interview or observe a set number of people. In other cases, the process of data collection and analysis may continue until the researchers find that no new issues are emerging. This may mean adopting a less formal and less rigid approach than that used in quantitative research. It is believed that people are constantly trying to attribute meaning to their experience.

Consequently, the methods used may be more open-ended, less narrow and more exploratory particularly when very little is known about a particular subject. The researchers are free to go beyond the initial response that the participant gives and to ask why, how, in what way etc. In this way, subsequent questions can be tailored to the responses just given. Qualitative research often involves a smaller number of participants. This may be because the methods used such as in-depth interviews are time and labour intensive but also because a large number of people are not needed for the purposes of statistical analysis or to make generalizations from the results.

The objectives of the two types of research and their underlying philosophical assumptions are simply different. The pragmatic approach to science involves using the method which appears best suited to the research problem and not getting caught up in philosophical debates about which is the best approach.

Pragmatic researchers therefore grant themselves the freedom to use any of the methods, techniques and procedures typically associated with quantitative or qualitative research. They recognise that every method has its limitations and that the different approaches can be complementary.

They may also use different techniques at the same time or one after the other. For example, they might start with face-to-face interviews with several people or have a focus group and then use the findings to construct a questionnaire to measure attitudes in a large scale sample with the aim of carrying out statistical analysis.

Depending on which measures have been used, the data collected is analysed in the appropriate manner. However, it is sometimes possible to transform qualitative data into quantitative data and vice versa although transforming quantitative data into qualitative data is not very common.

Being able to mix different approaches has the advantages of enabling triangulation. Triangulation is a common feature of mixed methods studies. It involves, for example:. In some studies, qualitative and quantitative methods are used simultaneously. In others, first one approach is used and then the next, with the second part of the study perhaps expanding on the results of the first.

For example, a qualitative study involving in-depth interviews or focus group discussions might serve to obtain information which will then be used to contribute towards the development of an experimental measure or attitude scale, the results of which will be analysed statistically.

As they aim to bring about positive change in the lives of the research subjects, their approach is sometimes described as emancipatory. It is not a neutral stance. The researchers are likely to have a political agenda and to try to give the groups they are studying a voice. As they want their research to directly or indirectly result in some kind of reform, it is important that they involve the group being studied in the research, preferably at all stages , so as to avoid further marginalising them.

The researchers may adopt a less neutral position than that which is usually required in scientific research. This might involve interacting informally or even living amongst the research participants who are sometimes referred to as co-researchers in recognition that the study is not simply about them but also by them. The findings of the research might be reported in more personal terms, often using the precise words of the research participants.

Whilst this type of research could by criticised for not being objective, it should be noted that for some groups of people or for certain situations, it is necessary as otherwise the thoughts, feelings or behaviour of the various members of the group could not be accessed or fully understood. Vulnerable groups are rarely in a position of power within society. For this reason, researchers are sometimes members of the group they are studying or have something in common with the members of the group.

Mixed designs is the best approach if the study requires both quantitative and qualitative designs to address the problem statement. Mixed design studies take significantly more time, more resources, and require the researcher to develop expertise in qualitative analysis techniques and quantitative analysis techniques.

Qualitative studies can use numbers, counts and even descriptive statistics. Using numbers does not mean the study has to be quantitative or mixed methods.

Quantitative and Qualitative Designs There are two main approaches to a research problem - quantitative and qualitative methods.

Choosing a Design The following table lists and describes the most common research designs used at Grand Canyon University.

Case Study And Historical Intent is to study and understand a single situation, which could be a leader, a classroom, a process, program, activity.

Causal Comparative Compare two groups with the intent of understanding the reasons or causes for the two groups being different. Narrative Describe the lives of individual s to get meaning from them.

Experimental Test an idea, treatment, program to see if it makes a difference. Quasi-experimental It is the same as experiment in that there is a control and test group. Phenomenology Studies a human experience at an experiential level such as understanding what it means for a woman to lose a child. Mixed Research Designs A mixed research design involves having both a quantitative design and qualitative design.
