1. Use it when you do not intend to generate results that will generalize the entire population. enables researchers to collect actionable insights from pre-screened and mobile-ready respondents. Therefore, the majority of non-probability sampling techniques include an element of subjective judgement. Learn everything about Net Promoter Score (NPS) and the Net Promoter Question. This sampling method depends heavily on the expertise of the researchers. Used when sampling bias has to be reduced. Researchers can send the survey to students belonging to a particular school, college, or university, and act as a sample. 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. Create online polls, distribute them using email and multiple other options and start analyzing poll results. There are several sampling methods that fall under probability sampling. To understand better about a population, the researcher will need only a sample, not the entire population. Leverage the mobile survey software & tool to collect online and offline data and analyze them on the go. When the researcher needs to observe whether a particular issue needs in-depth analysis, he applies this method. In an organization, for studying the career goals of 500 employees, technically, the sample selected should have proportionate numbers of males and females. This is contrary to probability sampling, where each member of the population has a known, non-zero chance of being selected to participate in the study. Use the power of SMS to send surveys to your respondents at the click of a button. A person with sound knowledge and ability on the subject matter can best perform if the person is permitted to conduct non-probability sampling. The respondents respond quickly as compared to people randomly selected as they have a high motivation level to participate. Because the researcher seeks a strategically chosen sample, generalizability is more of a theoretical or conceptual issue, and it is not possible to generalize back to the population (Palys & Atchison, 2014). Non-probability sampling speaks to a profitable gathering of examining strategies that can be utilized as a part of research that takes after subjective, blended techniques, and even quantitative research outlines. Which means there should be 250 males and 250 females. For general population studies intended to represent the entire population of a country or state, probability sampling is usually the preferred method. Don’t let your survey receive biased answers. Researchers also use this type of sampling to conduct research involving a particular illness in patients or a rare disease. In the judgmental sampling method, researchers select the samples based purely on the researcher’s knowledge and credibility. 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). Studies intended to use probability sampling sometimes end up using nonprobability samples because of characteristics of the sampling method.

Non Probability Sampling Probability sampling method is not suitable for all research studies. Once the researchers find suitable subjects, he asks them for assistance to seek similar subjects to form a considerably good size sample.
