A researcher designs an experiment to test how variables interact to influence job- seeking behaviours. The main purpose of the study was: a.Description Definition: Non-probability sampling is defined as a sampling technique in which the researcher selects samples based on the subjective judgment of the researcher rather than random selection. It is a less stringent method. This sampling method depends heavily on the expertise of the researchers. It is carried out by observation, and researchers use it widely for qualitative research. Non-probability sampling is a sampling method in which not all members of the population have an equal chance of participating in the study, unlike probability sampling. Each member of the population has a known chance of being selected. Non-probability sampling is most useful for exploratory studies like a pilot survey (deploying a survey to a smaller sample compared to pre-determined sample size). Researchers use this method in studies where it is impossible to draw random probability sampling due to time or cost considerations. Select your respondents Types of non-probability samplingHere are the types of non-probability sampling methods:
Convenience sampling is a non-probability sampling technique where samples are selected from the population only because they are conveniently available to the researcher.
Researchers choose these samples just because they are easy to recruit, and the researcher did not consider selecting a sample that represents the entire population.
This non-probability sampling method is very similar to convenience sampling, with a slight variation. Here, the researcher picks a single person or a group of a sample, conducts research over a period, analyzes the results, and then moves on to another subject or group if needed. Consecutive sampling technique gives the researcher a chance to work with many topics and fine-tune his/her research by collecting results that have vital insights.
Hypothetically consider, a researcher wants to study the career goals of male and female employees in an organization. There are 500 employees in the organization, also known as the population. To understand better about a population, the researcher will need only a sample, not the entire population. Further, the researcher is interested in particular strata within the population. Here is where quota sampling helps in dividing the population into strata or groups.
In the judgmental sampling method, researchers select the samples based purely on the researcher’s knowledge and credibility. In other words, researchers choose only those people who they deem fit to participate in the research study. Judgmental or purposive sampling is not a scientific method of sampling, and the downside to this sampling technique is that the preconceived notions of a researcher can influence the results. Thus, this research technique involves a high amount of ambiguity.
Snowball sampling helps researchers find a sample when they are difficult to locate. Researchers use this technique when the sample size is small and not easily available. This sampling system works like the referral program. Once the researchers find suitable subjects, he asks them for assistance to seek similar subjects to form a considerably good size sample. Non-probability sampling examplesHere are three simple examples of non-probability sampling to understand the subject better.
When to use non-probability sampling?
Advantages of non-probability samplingHere are the advantages of using the non-probability technique

Sampling with QuestionPro AudienceWhy restrict yourself to a limited population when you can get access to 22 million+ survey respondents around the globe? Every day, QuestionPro Audience enables researchers to collect actionable insights from pre-screened and mobile-ready respondents. Don’t let your survey receive biased answers. Good survey results are derived when the sample is truly representative of the population. What type of sampling is used in qualitative research that involves selecting cases that disconfirm?Purposeful sampling is widely used in qualitative research for the identification and selection of information-rich cases related to the phenomenon of interest.
What do we call data that are used for a new study but was collected by an earlier researcher for a different set of research questions?Secondary data means data collected by someone else earlier. Surveys, observations, experiments, questionnaire, personal interview, etc. Government publications, websites, books, journal articles, internal records etc. Always specific to the researcher's needs.
What do we call data that are used for a new study?An advantage of using primary data is that researchers are collecting information for the specific purposes of their study.
Which of the following is a method that is commonly used in qualitative research?The three most common qualitative methods, explained in detail in their respective modules, are participant observation, in-depth interviews, and focus groups.
