There may be other assumptions that are unique to your research design. What are research limitations? Some typical limitations are sample size, methodology constraints, length of the study, and response rate. There may be unknown conditions or factors at the facility where the participants reside, work, or study that could bias the responses of the participants.
If you are collecting data from the elderly, if is possible that some of their recollections of events, situations, and feelings could be questionable. The number of participants or subjects is enough from which to adequately draw conclusions. In qualitative methods, you will want the numbers of participants to reach a level at which saturation of the data is achieved — no new data or meaning units are being discovered.

John Stephen Martin, Jr. Dropouts Who Return for Their Ged: Journey to the Presidency: Women in the Integrated Circuit: Internationalization in Community Colleges: The Freshman Academy Impact: Remember that theoretical studies, like data-based studies, need to have their research design spelled out from the start.
But even if your dissertation is more empirically focused, it could still be entirely literature-based. You might choose to conduct a review of a field of work. What does the research literature in this field tell us about x?
While all dissertations will include a literature review, it is possible to produce a dissertation that is entirely based on a review of the literature. If you do this, it is important to review the literature from an explicit angle and identify some themes to make the review distinctive. You might, for example, explore empirical debates in your chosen field across different countries or time periods.
Whilst it is possible for dissertations to be entirely literature-based, the most common form of dissertation takes the form of a case study. Here the focus of attention is on a particular community, organisation or set of documents. The attraction of this kind of dissertation is that it stems from empirical curiosity but is at the same time practical. You may be interested in a wider question but a case study enables you to focus on a specific example.
A major challenge in case study dissertations is connecting your own primary research or re-analysis with the broader theoretical themes and empirical concerns of the existing literature.
Most dissertations demand either primary or secondary research. In other words, you usually have to analyse data that you have either collected yourself or data that is already available. The reason for this is that the questions dissertations usually address take the following form: Why is x happening? Why is x changing? These questions demand primary or secondary analysis of data. Case Study 9 Think hard before you decide to undertake empirical research: Secondary analysis is when you analyse data which was collected by another researcher.
It allows the researcher to explore areas of interest without having to go through the process of collecting data themselves in the field. The problem with using fieldwork methods in an undergraduate dissertation, however, is that they are costly in terms of time which is relatively scarce in your final year! You may choose, therefore, to undertake secondary research, analysing existing data.
There are a range of documents that already contain research data that you can analyse. You may, for example, be interested in exploring whether gender stereotypes in the media are changing. This might entail content analysis of newspapers, magazines, video or other media over different time periods.
Here you would not be collecting your own data but instead would be analysing existing documents. Download Case Study 6 Media research.
If you are interested, for example, in doing historical research, you may need to visit archives. Government reports and autobiographies may also be used as data. Other documents include official statistics, datasets statistical data , and banks of interview transcripts which are all freely available to the academic community.
Increasingly, documents, databases and archives are readily accessible online. Research Methods tutors on your course will be able to advise on the availability and accessibility of such data sets. There are some advantages of doing secondary analysis, particularly if you are doing a quantitative study. You will be able to work with much larger datasets than you could have collected yourself.
This has the following advantages:. Quantitative data may also result from non-participant observations or other measurements e. Also, sometimes data that are collected through qualitative processes participant observation, interviews are coded and quantified.
Your research methods tutor can give you further information on these types of data, but here are some common quantitative data collection methods and their definitions:. A series of questions that the respondent answers on their own. Self-completion questionnaires are good for collecting data on relatively simple topics, and for gaining a general overview of an issue.
Questionnaires need to have clear questions, an easy to follow design, and not be too long. Similar to a self-completion questionnaire, except that the questions that are asked by an interviewer to the interviewee.
The same questions are read out in the same way to all respondents. There will typically be a fixed choice of answers for the respondents.
Watching people and recording systematically their behaviour. Prior to the observation, an observation schedule will be produced which details what exactly the researcher should look for and how those observations should be recorded. If you are conducting a qualitative analysis you are likely to wish to use at least some original material. This may be collected through in-depth interviews, participant observation recordings and fieldnotes, non-participant observation, or some combination of these.
Below are some data collection methods that you might want to use for your dissertation:. A way of asking questions which allows the interviewee to have more control of the interview.
A form of interviewing where there are several participants; there is an emphasis in the questioning on a tightly defined topic; the accent is on interaction within the group and the joint construction of meaning. The moderator tries to provide a relatively free rein to the discussion. This involves studying people in naturally occurring settings. The researcher participates directly in the setting and collects data in a systematic manner.
The researcher will observe behaviour, listen to conversations, and ask questions. Spend some time looking at general books about research - they will give you an overview of the data collection methods available and help you to make the best choice for your project. Bryman would be a useful starting point. For any piece of research you conduct, be it empirically based quantitative or qualitative or library based, its methods must be justified. You need to show in the final dissertation how you have given consideration to different methods, and why you have chosen and eliminated these.
Often in early supervision meetings they ask students to justify their reasons for choosing a library-based or an empirical study. Todd, Smith and Bannister , p This was particularly useful for one of our respondents:. With other essays you can rush them if you have to Todd, Bannister and Clegg, , p …. My reasons for data collection is literature based as my research question involved sensitive subjects which would have been unsuitable for primary data collection.
Level 6 students at Sheffield Hallam University I chose primary data because it would enable me to build skills that would be useful for postgraduate study. Level 6 students at Sheffield Hallam University It will involve primary data, secondary data, quantitative and qualitative research methods, lit reviews, theory and policy studies and an exploration of alternatives.
My dissertation is to be based around the experience of 'poverty', as poverty is the experience. Theories and policies are not. However, to do justice to the subject, theories and policies will be included so Iam able to demonstrate where failures in the system may exist.
Level 6 students at Sheffield Hallam University. Research must be conducted in a sensible and ethical manner; data must be analysed and presented in a rational manner.
