By conditions , we mean the units i. These purposive sampling techniques include maximum variation sampling , homogeneous sampling, typical case sampling , extreme or deviant case sampling , total population sampling and expert sampling. Whilst total population sampling is infrequently used, there are specific types of research where total population sampling can be very useful. These extreme or deviant cases are useful because they often provide significant insight into a particular phenomenon, which can act as lessons or cases of best practice that guide future research and practice. Use of top 5 social networks i. They draw on one of four broad quantitative research designs i.

Duplication , Route B: Overall, qualitative dissertations will be very different in approach, depending on the particular route that you adopt e. Non-managers As the examples above highlight, relationship-based research questions are appropriate to set when we are interested in the relationship, association, trend, or interaction between one or more dependent e. These data-driven dissertations tend to be empirically-focused , and are often in fields where there is little theory to help ground or justify the research, but also where uncovering the stylized fact and its antecedents makes a significant contribution all by itself.

As dissertayion, for researchers following a quantitative research design, non-probability sampling techniques can often be viewed as an inferior alternative to probability quxlitative techniques. Daily calorific intake Group: Even if you know that non-probability sampling fits with the research strategy guiding your dissertation, it is important to choose the appropriate type of non-probability sampling techniques.

In our example of the laer, university students, if we were only interested in achieving a sample size of say students, we may simply stand at one of the main entrances to campus, where it would be easy to invite the many students that pass by to take part in the research.

Quantitative dissertations When we use the word quantitative to describe quantitative dissertationswe do not simply mean that the dissertation will draw on quantitative research methods or statistical analysis techniques.

Data-driven dissertations is that they place most importance on the theoretical contribution that you make.

However, this is not the case for researchers following a qualitative research design. Data-driven dissertations and Route 3: In some cases, you don’t even redo the previous study, but simply request the original data that was collected, and reanalyse it to check that the original authors were accurate in their analysis techniques. Therefore, with typical case sampling, you cannot use the sample to make generalisations to a population, but the sample could be illustrative of other similar samples.
