About us






























Sampling for Ph.D. Research

In research terms, a sample is a group of people, objects, or items that are taken from a larger population for measurement. The sample should be representative of the population to ensure that we can generalize the findings from the research sample to the population. The selection of samples is decided, based on factors such as nature of the study, the size of the universe, the size of sample, degree of precision derived and availability of resources. The need of having a sample is very important because it would be impracticable to survey the whole population. In addition, the budget constraints prevent from surveying the entire population. Finally, the researcher must collect the results quickly because of time constraints.

Two general approaches to sampling are used in social science research. With probability sampling, all elements (e.g., persons, households) in the population have some opportunity of being included in the sample, and the mathematical probability that any one of them will be selected can be calculated.

With non-probability sampling, in contrast, population elements are selected based on their availability (e.g., because they volunteered) or because of the researcher's personal judgment that they are representative. The consequence is that an unknown portion of the population is excluded (e.g., those who did not volunteer).

At Ph.D. Assistance, our experts help you to select appropriate sampling based on your research objective, chosen research design, data collection method, and target population.

Sampling Features at Ph.D. Assistance

Several types of sampling techniques are available as follows:

Random Sampling:

This is the easiest form of probability technique. In this method, each respondent will get equal chances. However, if the target population is high, then it is very difficult to define the exact sample size (Saunders et al., 2003).

Systematic sampling:

This method is commonly referred as the Nth name selection method. In this method, each Nth record can be selected from the target population (Saunders, 2003).

Stratified sampling:

Based on the characteristics, the research will classify the research population. After that the participants will be selected by the researcher from (Saunders, 2003).

Convenience sampling:

In this method, a subset of participants will be selected by the researcher due to time and cost constrictions. This method often assumes that the target population is represented by the subset of the population. In this method, subjects with convenient accessibility are generally selected by the researcher (Saunders 2003).

Quota Sampling

Perhaps most commonly used in face-to-face interviewing. Interviewers on the street are usually looking for a specific type of respondent – age, gender are the most frequently used 'quota controls.' Quotas are given to interviewers and are organized so that the final sample is representative of the population. It is impossible to estimate the accuracy of the sample because it is not random.

Snowball Sampling:

This approach is often used when trying to interview hard to reach groups such as unemployed people or Black or Minority Ethnic residents. You initially contact a few potential respondents, interview them and then ask if they know of anybody else with the same characteristics you are looking for.

Self-Selection:

This technique is self-explanatory – respondents themselves decide whether to take part in the survey or not

Judgment sampling:

In this method, the subset will be selected by the researchers based on their judgment. This method is often preferred by researcher while evaluating the technical issues in sampling technique. The selected participants will be posted in the best position to achieve better solution (Saunders, 2003). The following table 5 shows the sampling method adopted by the researcher in this study:

To ensure that the chosen sample was an envoy of the complete statistically significant population it is essential to measure the size of the population. Sampling occupies any part of a target population or universe as a representative of that population or universe.
