In sociology and statistics research, snowball sampling[1] (or chain sampling, chain-referral sampling, referral sampling,[2][3] qongqothwane sampling[4]) is a nonprobability sampling technique where existing study subjects recruit future subjects from among their acquaintances. The document emphasizes Non-probability sampling refers to methods where researchers select participants based on subjective judgment rather than randomization, leading to unequal chances of selection for units in the target population. Understanding the differences, advantages, and applications of each method is essential for selecting the appropriate sampling strategy for a given research study. It also explores different types of nonprobability samples, including accidental, haphazard, convenience, modal instance, purposive, expert, quota, snowball, and heterogeneity sampling.

The document emphasizes the importance of selecting a true Jul 31, 2017 · PDF | Besides emphasizing the need for a representative sample, in this chapter, we have examined the importance of sampling. It addresses the advantages and disadvantages of sampling techniques, differentiating between probability and non-probability sampling methods, along with specific sampling strategies like simple random, systematic, and stratified sampling. For each type, it provides a This document discusses non-probability sampling techniques. Additionally, it outlines the steps involved in the sampling process and considerations for selecting Sampling distribution of sample statistic: The probability distribution consisting of all possible sample statistics of a given sample size selected from a population using one probability sampling. Non-Probability Sampling-- Focus Group Technique: The sample is selected on the basis of convenience and expertise. Non-probability Probability and non-probability sampling techniques are used to select samples from populations. Non-probability techniques like convenience, judgmental, snowball, and quota sampling rely Feb 4, 2023 · Non-probability sampling techniques have been discussed with the necessary example so that the readers can easily understand which method will be more appropriate for their study. However, they can be easily associated with similar educational contexts. Non-probability sampling is a technique where researchers select samples based on subjective judgment rather than random selection, making it useful for qualitative research, exploratory studies, and when faced with time or budget constraints. Non-probability sampling does not give all members an equal chance, relying instead on subjective judgment in techniques like convenience sampling. The key differences Oct 5, 2014 · Nonprobability Sampling Designs. Common techniques include convenience sampling, quota sampling, judgmental sampling, and snowball sampling, each with specific applications and pros and cons such as ease of data Jul 23, 2025 · Two primary categories of sampling techniques are probability sampling and non-probability sampling. Non-probability sampling methods are sampling techniques where some elements have no chance of being selected, and the probability of selection for each element is unknown. Non probability Sampling techniques. Non-probability sampling methods include judgment sampling, convenience sampling, quota sampling, and snowball sampling. pdf), Text File (. Non-probability sampling involves selecting samples based on the researcher's judgment rather than random selection. Thus the sample group is said to grow like a rolling snowball. ppt), PDF File (. Convenience sampling involves selecting subjects based on their easy accessibility, leading to potential biases. Accidental, haphazard, convenience Modal instance Purposive Expert Quota Snowball Heterogeneity sampling. There are two main types of sampling: probability sampling, where every member has a chance of being selected, and non-probability sampling, where not every member has an equal chance. Key types include convenience, quota, judgmental, and snowball sampling, which provide faster and more cost-effective results but may not accurately This document discusses different sampling methods used in research. Consecutive sampling is similar but seeks to include all accessible subjects. Various methods are outlined, including convenience sampling, purposive sampling, quota sampling, and snowball sampling, each with its own advantages and disadvantages. It defines key terms like population, sample, probability sampling, and non-probability sampling. Likely to misrepresent the population May be difficult or impossible to detect this misrepresentation. This document discusses non-probability sampling, a technique where the likelihood of selecting any member for a sample cannot be calculated. This document discusses different sampling techniques used in research. This presentation educates you about Non-Probability Sampling, Types of non-probability sampling, When to use non-probability sampling?, Advantages of non-probability sampling and difference. Some common non-probability This document summarizes probability and non-probability sampling methods. NON PROBABILITY SAMPLING if every element in a population does not have an equal chance of being selected. Quota sampling ensures equal representation onal contexts within the country of Malta. In the last section, an application of two non-probability sampling techniques – convenience and voluntary sam KEYWORDS: probability sampling, non-probability sampling, qualitative research methods, quantitative research methods. Aug 23, 2021 · 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. Types of Nonprobability Samples. It details various techniques within these categories, such as simple random sampling, stratified sampling, and cluster sampling, emphasizing their advantages and limitations. It then describes several common non-probability sampling methods: convenience sampling, which uses readily available participants; snowball sampling, which uses referrals from initial participants to recruit more; purposive sampling Non-probability sampling methods allow researchers to select sample subjects without assigning probabilities, which can lead to findings that are not generalizable to the population. pptx - Free download as Powerpoint Presentation (.
