Sampling techniques As we have mentioned above, when we are interested in a population, we typically study a sample of that population rather than attempt to study the whole population e. For example, if the population we were interested in was all million or more Facebook users, each of these Facebook users would be a unit.

Snowball sampling relies on referrals from initial subjects to generate additional subjects. Others still simply aim to make it easier and less costly to select units for your sample e.
These include convenience sampling, judgment sampling, quota sampling, and snowball sampling. In sampling, a population signifies the units that we are interested in studying. We visit each household in that street, identify all adults living there, and randomly select one adult Dissertation sampling methods each household.
The sample reflects the characteristics of the population from which it is drawn. Types of probability, sampling: But a person living in a household of two adults has only a one-in-two chance of selection.
Dissertation sampling methods They have therefore been given fictional names, so as to make the research more readable. If we selected a sample size of units, we would need to interview students.
A stratum is a subset of the population that share at least one common characteristic. For example, consider a street where the odd-numbered houses are all on the north expensive side wind of the road, and the even-numbered houses are all on the south cheap side. The researcher selects the sample based on judgment.
Example Imagine we were using structured interviews i. Systematic sampling edit main article: Examples of stratums might be males and females, or managers and non-managers. The following figure summarizes the steps to selection of participants: These units could be people, cases and pieces of data.
Random sampling is then used to select a sufficient number of subjects from each stratum. Therefore, we choose to study just a sample of these Facebook users. Sometimes they may be entirely separate for instance, we might study rats in order to get a better understanding of human health, or we might study records from people born in in order to make predictions about people born in However, if you are still just trying to get to grips with sampling, we recommend that you start by reading the article, Sampling: However an indepth correlation or bivariate analysis was not conducted due to the low number of graduate respondents, and also due to the fact that the study was mainly concerned with the viewpoint of the organization, and not necessarily that of the graduates.
Those PhD advisors who had mentoring experience with these phases of the dissertation process were selected. Sampling bias Sampling bias occurs when the units that are selected from the population for inclusion in your sample are not characteristic of i.
Describe what you are studying Explain the types of sampling technique available to you State and describe the sampling strategy you used Justify your choice of sampling strategy In the article, How to structure the Sampling Strategy section of your dissertationwe discuss each of these steps, providing an example to illustrate how to write up the Sampling Strategy section.
This differs from stratified sampling, where the stratums are filled by random sampling. New Cars, Used Cars for Sale, car However, in the more general case this is not usually possible or practical.
Perhaps our population is not Facebook users, but frequent, male Facebook users in the United States. Hence, because the selection of elements is nonrandom, nonprobability sampling does not allow the estimation of sampling errors.
There are no strict rules to follow, and the researcher must rely on logic and judgment. In nonprobability sampling, the degree to which the sample differs from the population remains unknown. This is because the different components of your research strategy i.
Snowball sampling is a special nonprobability method used when the desired sample characteristic is rare. The samples of graduates that were chosen to partake in the quantitative study are too small to constitute a probability sample of graduates within London or UK.
Whilst we discuss more about sampling and why we sample later in this article, the important point to remember here is that a sample consists of only those units in this case, Facebook users from our population of interest i.Methods Section: Chapter Three The methods section, or chapter three, of the dissertation or thesis is often the most challenging for graduate students.
