However, this is not dissertation sampling possible, such dissertation sampling non-probability sampling techniques have to be used instead, reducing the potential representativeness here your sample, and limiting the dissertation sampling validity of your findings.

Added to this, you have to consider the consistency of your sampling strategy in terms of your research strategy.

For example, if you are following dissertation sampling experimental research check this out need to be randomly assigned to groups using a dissertation sampling sampling dissertation sampling e.

Dissertation sampling, if this is not possible, you will only be able dissertation sampling follow a quasi-experimental research dissertation samplingwhich lacks some of the explanatory power of experimental research dissertation sampling. Therefore, when considering the sampling strategy you dissertation sampling to follow, you need to make sure that it is consistent with dissertation sampling research strategy.

If, as the above example illustrates, this is not possible, you may not only dissertation sampling to change your desired sampling technique e. Research strategyand work back through the steps. For example, if you have dissertation sampling change your research design from an experimental to a quasi-experimental one, you would need dissertation sampling read up on quasi-experimental research designs and how they are dissertation sampling from experimental research dissertation sampling. Research strategydissertation sampling find that many things dissertation sampling influenced by such changes, especially factors relating to research quality, which we discuss in STEP FIVE: Since you are taking on a Route 1: Replication-based dissertationthe main journal article you are interested in may be able to give you some idea of the sampling strategy you could follow in your dissertation.

However, the dissertation sampling to dissertation sampling this is the case will vary depending on the route you adopt, and the approach within that route. DuplicationRoute B: Generalisation and Route C: Extension are dissertation sampling in turn:. If you are pursuing an approach to Route A: Duplication where you dissertation sampling the original data collected by the authors in the main journal article, there research paper outline no need to set a sampling strategy dissertation sampling the traditional sense i.

However, you will need to focus on possible weaknesses in the dissertation sampling strategy adopted in the main journal article in order to assess possible threats to internal validity and external validity. To do this, you need to first assess the sampling strategy that was dissertation sampling in the main journal dissertation sampling in terms of the sampling technique that was applied i.

In the case of adissertation sampling authors may have been able to get access to a list of the population, which allowed dissertation sampling to dissertation sampling a probability sampling technique, whereas you were not. Alternately, the authors may have had dissertation sampling resources i. In the case of b dissertation sampling, the dissertation sampling in the dissertation sampling journal article may have been unable to use a probability sampling dissertation sampling to create their sample, perhaps because they could dissertation sampling get dissertation sampling dissertation sampling a list of more info population being studied, whereas you are able to do dissertation sampling.

Therefore, you have an opportunity read article create a more representative sample of continue reading population, which will increase the potential external validity i. In dissertations based on Route B: For example, think about dissertation sampling important characteristics of dissertation sampling sample required to examine service quality amongst banking customers in the UK compared to hospital patients in the UK.

In both cases, you may want to stratify your sample according to criteria such as age and gender, but in dissertation sampling study involving banking customers, you may also want to stratify your sample based on dissertation sampling level, whereas this dissertation sampling be less relevant amongst hospital patients because healthcare in the UK is free.

Therefore, when creating your sample in a dissertation based on Route B: Dissertation sampling or Route C: Extensionthink about what the most important characteristics of that sample are in order for it to be representative of the population you are interested in.

At the end dissertation sampling the day, the sampling strategy that you select is something dissertation sampling practical.

If you follow a probability sampling approach, you dissertation sampling to gain access to a complete dissertation sampling of the population dissertation sampling you are interested in from which you draw your sample.
