For this reason, there are two types of <a href=\"https:\/\/www.questionpro.com\/blog\/types-of-sampling-for-social-research\/\">sampling<\/a>: the random or probabilistic sample and the non-probabilistic one. In this case, we will talk in-depth about non-probability sampling. Keep reading!<\/p>\n\n\n\n\n\n<h2 class=\"wp-block-heading\">What is non-probability sampling?<\/h2>\n\n\n\n<p><b>Definition:<\/b> <span style=\"font-weight: 400;\">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 <\/span><a href=\"https:\/\/www.questionpro.com\/blog\/qualitative-market-research\/\"><span style=\"font-weight: 400;\">qualitative research.<\/span><\/a><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Non-probability sampling is a method in which not all population members have an equal chance of participating in the study, unlike <a href=\"https:\/\/www.questionpro.com\/blog\/probability-sampling\/\">probability sampling<\/a>. Each member of the population has a known chance of being selected. Non-probability sampling is most useful for exploratory studies like a <a href=\"https:\/\/www.questionpro.com\/blog\/pilot-survey\/\">pilot survey<\/a> (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.<\/span><\/p>\n\n\n<blockquote>\n<p><strong>LEARN ABOUT:<\/strong> <a href=\"https:\/\/www.questionpro.com\/blog\/survey-sampling\/\">Survey Sampling<\/a><\/p>\n<\/blockquote>\n\n\n<h2 class=\"wp-block-heading\"><br>Types of non-probability sampling<\/h2>\n\n\n\n<p>Here are the types of non-probability sampling methods:<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"992\" height=\"970\" src=\"https:\/\/www.questionpro.com\/blog\/wp-content\/uploads\/2021\/04\/Types-of-Non-probability-Sampling-min.jpg\" alt=\"Types of non probability sampling\" class=\"wp-image-118629\"\/><\/figure><\/div>\n\n\n<ul>\n<li><h3>Convenience sampling<\/h3><\/li>\n<\/ul>\n\n\n\n<p><b><\/b><b><\/b><a href=\"https:\/\/www.questionpro.com\/blog\/convenience-sampling\/\">Convenience sampling<\/a> 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.<br>Ideally, in research, it is good to test a sample that represents the population. But, in some research, the population is too large to examine and consider the entire population. It is one of the reasons why researchers rely on convenience sampling, which is the most common non-probability sampling method, because of its speed, cost-effectiveness, and ease of availability of the sample.<\/p>\n\n\n\n<ul>\n<li><h3>Consecutive sampling<\/h3><\/li>\n<\/ul>\n\n\n\n<p>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.<\/p>\n\n\n\n<ul>\n<li><h3>Quota sampling<\/h3><\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-align-left\"><b><\/b><span style=\"font-weight: 400;\">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 <a href=\"https:\/\/www.questionpro.com\/blog\/sample\/\">sample<\/a>, not the entire population. Further, the researcher is interested in particular strata within the population. Here is where <a href=\"https:\/\/www.questionpro.com\/blog\/quota-sampling\/\">quota sampling<\/a> helps in dividing the population into strata or groups.<\/span><\/p>\n\n\n\n<ul>\n<li><h3>Judgmental or Purposive sampling<\/h3><\/li>\n<\/ul>\n\n\n\n<p><b><\/b><span style=\"font-weight: 400;\">In the <a href=\"https:\/\/www.questionpro.com\/blog\/judgmental-sampling\/\">judgmental sampling<\/a> method, researchers select the samples based purely on the researcher\u2019s knowledge and credibility. In other words, researchers choose only those people who they deem fit to participate in the research study. <\/span>Judgmental or <a href=\"https:\/\/www.questionpro.com\/blog\/purposive-sampling\/\">purposive sampling<\/a> 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.<\/p>\n\n\n\n<ul>\n<li><h3>Snowball sampling<\/h3><\/li>\n<\/ul>\n\n\n\n<p><a href=\"https:\/\/www.questionpro.com\/blog\/snowball-sampling\/\">Snowball sampling<\/a> 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.<\/p>\n\n\n<blockquote>\n<p><strong>LEARN MORE:<\/strong> <a href=\"https:\/\/www.questionpro.com\/blog\/simple-random-sampling\/\">Simple Random Sampling<\/a><\/p>\n<\/blockquote>\n\n\n<h2 class=\"wp-block-heading\"><br>Non-probability sampling examples<\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">Here are three simple examples of non-probability sampling to understand the subject better.<\/span><\/p>\n\n\n\n<ol>\n<li><span style=\"font-weight: 400;\">An example of convenience sampling would be using student volunteers known to the researcher. Researchers can send the <a href=\"https:\/\/www.questionpro.com\/blog\/surveys\/\">survey<\/a> to students belonging to a particular school, college, or university, and act as a sample.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">In an organization, for studying the career goals of 500 employees, technically, the sample selected should have proportionate numbers of males and females. Which means there should be 250 males and 250 females. Since this is unlikely, the researcher selects the groups or strata using quota sampling.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Researchers also use this <a href=\"https:\/\/www.questionpro.com\/blog\/types-of-sampling-for-social-research\/\">type of sampling<\/a> to conduct research involving a particular illness in patients or a rare disease. Researchers can seek help from subjects to refer to other subjects suffering from the same ailment to form a subjective sample to carry out the study.<\/span><\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">When to use non-probability sampling?<\/h2>\n\n\n\n<ul>\n<li><span style=\"font-weight: 400;\">Use this type of sampling to indicate if a particular trait or characteristic exists in a population.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Researchers widely use the non-probability sampling method when they aim at conducting qualitative research, pilot studies, or exploratory research.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Researchers use it when they have limited time to conduct research or have budget constraints.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">When the researcher needs to observe whether a particular issue needs <a href=\"https:\/\/www.questionpro.com\/blog\/in-depth-analysis\/\">in-depth analysis<\/a>, he applies this method.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Use it when you do not intend to generate results that will generalize the entire population.<\/span><\/li>\n<\/ul>\n\n\n<blockquote>\n<p><strong>LEARN MORE:<\/strong> <a href=\"https:\/\/www.questionpro.com\/blog\/population-vs-sample\/\">Population vs Sample<\/a><\/p>\n<\/blockquote>\n\n\n<h2 class=\"wp-block-heading\"><br>Advantages of non-probability sampling<\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">Here are the advantages of using the non-probability technique<\/span><\/p>\n\n\n\n<ul>\n<li><span style=\"font-weight: 400;\">Non-probability sampling techniques are a more conducive and practical method for researchers deploying surveys in the real world.
