Female, British university students In terms of the first descriptive research question about daily calorific intake , we are not necessarily interested in frequencies , or using a measure of central tendency or measure of spread , but instead want understand what percentage of American men and women exceed their daily calorific allowance. Building , the building of new theory goes further because even if the theories you are building on are well-established, you are likely to have to create new constructs and measurement procedures in order to test these theories. However, it is also common when using descriptive research questions to measure percentages and proportions , so we have included some example descriptive research questions below that illustrate this. Replication-based dissertation is right for you, and if so, which of these routes you want to follow, start with our introductory guide: We provide some examples below:. The different purposive sampling techniques can either be used on their own or in combination with other purposive sampling techniques.

Research quality All research has limitations , which negatively impact upon the quality of the findings you arrive at from your data analysis. Whilst typical case sampling can be used exclusively, it may also follow another type of purposive sampling technique, such as maximum variation sampling, which can help to act as an exploratory sampling strategy to identify the typical cases that are subsequently selected. They follow research designs that heavily influence the choices you make throughout the research process, as well as the analysis and discussion of ‘findings’ i. These units may exhibit a wide range of attributes, behaviours, experiences, incidents, qualities, situations, and so forth. However, it is also common when using descriptive research questions to measure percentages and proportions , so we have included some example descriptive research questions below that illustrate this. If we were to examine the differences in male and female students, for example, the number of students from each group that we would include in the sample would be based on the proportion of male and female students amongst the 10, university students.

Combining or Route C: Qualitative research designs are generally assessed in terms of their credibilityconfirmabilitydependability and transferabilityamongst other factors.

Each of these three routes reflects a very different type of quantitative dissertation that you can take on.

However, irrespective of the particular route that you adopt when taking on a quantitative dissertation, there are a number of dissertaiton characteristics to quantitative dissertations: Replication-based dissertations Route 2: These 10, students are our population N.

In such cases, the use of well-established theories helps when testing these theoretical combinations.

Daily calorific intake Groups: In most cases, replication is associated with duplication. In reality, it doesn’t matter what you call them.

We emphasize the words testingcombining and building because these reflect three routes that you can adopt when carrying out a theory-driven dissertation: Qualitative research takes a particular approach towards the research processthe setting of research questionsthe development and use of qualitativsthe choice of research strategythe way that paerd are presented and discussed, and so forth.

In sampling, units are the things that make up the population.

What are the most important factors that influence the career choices of Australian university students? There are theoretical and practical reasons for using non-probability sampling. We simply give them these laer because a they reflect three different routes that you can follow when doing a dissertatiln dissertation i.

Often, descriptive research questions focus on only one variable and one group, but they can include multiple variables and groups. They follow research designs that heavily influence the choices you make throughout the research process, as well as the analysis and discussion of ‘findings’ i.

This is the general intent of research that is guided by a quantitative research design. For example, you may choose to select only those units to be included in your sample that you feel will exhibit the problem or issue you are interested in finding.

Non-probability sampling | Lærd Dissertation

We may then choose to examine this data by presenting the frequenciesas well as using a measure of central tendency and a measure of spread [see the section on Data Analysis to learn more about these and other statistical tests]. When defining the population, need to explain the specific characteristics of the population that make it appropriate to use a total population sampling. However, irrespective of the route that you choose to follow, there are a number of broad characteristics to qualitative dissertations: Well-known theories include social capital theory Social Sciencesmotivation theory Psychologyagency theory Business Studiesevolutionary theory Biologyquantum theory Physicsadaptation theory Sports Scienceand so forth.

For example, critical case sampling may be used to investigate whether a phenomenon is worth investigating further, before adopting a maximum variation sampling technique is used to develop a wider picture of the phenomenon.

In the sections that follow, we briefly describe the main characteristics of qualitative, quantitative and mixed methods dissertations. However, we plan to introduce guides to assess research quality in qualitative research designs in the not too distant future.

For example, imagine that we are interested in studying some of the psychological aspects of people living disserfation a rare disease quwlitative affects just 1 person in every 1 million people e. These non-probability sampling techniques are briefly set out in the next section.

Qualitative, quantitative and mixed methods dissertations What are they and which one should I choose? With such wide coverage of the population of interest, there is also a reduced risk of missing potential insights from members that are not included.

They can be underpinned by one of a number of research paradigms e.

Whilst making generalisations from the sample to the population under study may be desirable, it is more often a secondary consideration. If you are performing a piece of descriptivequantitative research for your dissertation, you are likely qualitahive need to set quite a number of descriptive research questions.
