Duplication ; Route B: Goal A explore whether there is a relationship between different variables; Goal B predict a score or a membership of a group; or Goal C find out the differences between groups you are interested in or treatment conditions that you want to investigate: Replication-based dissertations Route 2: Do stressed males and females respond differently to different stress-reduction therapies? If there is no interaction, follow-up tests can still be performed to determine whether any change in stress levels was simply due to one of the factors i. We show you which parts of this SPSS Statistics output you need to interpret and how to write up your results.

This needs to be very specific. In our experience, understanding and setting the research paradigm is without doubt the most confusing part of the dissertation process for students. By contrast, more exploratory research in the social sciences is often found to use qualitative research designs. In most cases, replication is associated with duplication. We discuss quantitative dissertations , qualitative dissertations and mixed methods dissertations in turn: However, if you are predicting the score or a membership of a group i.

If a difference in the research paradigm underpinning the research in the main journal article and your dissertation is not a major justification for your choice of route or the approach within that route, we would suggest ignoring the research paradigm used in the main journal article, and simply thinking about the research paradigm you want to use in your dissertation. Third, many students find it the most challenging chapter of their dissertation to get to grips with and write in a clear and consistent way.

Duplicationyou would typically not be expected to make any changes to the research design used in the main journal article when setting the research design for your dissertation.

It states the specific sampling technique that you actually used e. Replication-based dissertations Route 2: For example, a researcher may have proposed a new theory in a journal article, but not yet tested it in the field by collecting and analysing data to see if the theory makes sense.

However, there are some instances where, from a practical standpoint, you may find that it is not possible to use the same research design, perhaps because an experimental research design was used, but you are unable to randomly selected people from the population you can get access to, forcing you to use a quasi-experimenta l research design.


In reality, it doesn’t matter what you call them. We have to be careful when using deskgn word relationship because in statistics, it refers to a particular type of research design, namely experimental research designs where it is possible to measure the cause and effect between two or more variables; that is, it is possible to say that variable A e.

Everything you need to complete your data analysis.

Take the following examples in red text: Do stressed males and females respond differently to different stress-reduction therapies? Whilst it is best to consult your dissertation guidelines to see which components you are required to include, your research strategy generally dissetration that you are able to describeexplain and justify: In other words, you take a piece of published research and repeat it, typically in an identical way to see if the results that you obtain are the same as the original authors.

By contrast, the findings in a dissertation guided by a constructivist research paradigm and a qualitative research design would more likely be assessed in terms of their credibility, confirmability, dependability, and transferability, amongst other factors. If your between-subjects factor only has two groups, you will not need to run any post hoc tests.

By contrast, more exploratory research in the social sciences deskgn often found to use qualitative research designs.

In the sections that follow, we describe the main characteristics of these three routes. Replication-based dissertations and Route 2: Which part of this output you should interpret will depend on whether your data passed the assumptions tests in Step 1 above. STAGE 6 Setting your research strategy Once you laed a good understanding of the theoretical components involved in your main journal articleyour choice of routeand the approach within that route, it is time to set the research strategy you will use in your dissertation.


If you do not know much about quantitative research and quantitative research questions at this stage, we dissdrtation recommend that you first read the article, Quantitative research questions: In fesearch respects, they are opposing approaches to research.

DuplicationRoute B: For example, we could relate age to how frequently the students used Facebook each week. However, this article focuses solely on quantitative research questions.

GOAL A Exploring the relationship between variables Are you trying to determine if there is a relationship between two or more drsign, and what this relationship is? Even the way that you present your findings Presenting Findingsassess their quality Research Quality and make ethical decisions Research Ethics are all interlinked. Sometimes, the focus of data-driven dissertations is entirely on discovering whether the stylized fact exists e.

Mixed ANOVA using SPSS Statistics

A majority of students at the undergraduate, master’s, and even doctoral level will take on a Route 1: This would involves testing for differences in back pain scores i. Nonetheless, you may still find our introductions to qualitative dissertations and mixed methods dissertations useful, if only to decide whether these types of dissertation are for you.

This is not uncommon when working with real-world data rather than textbook examples. Attitudes towards music piracy Independent variable: They lafrd the theoretical insights arising from the findings in light of the research questions, from which tentative conclusions are made.

FOURTH Decide whether the dependent variable or group s should be included first, last or in two parts Sometimes it makes more sense for the dependent variable to appear before the group s you are interested in, but sometimes it is the opposite way around.
