2022年8月9日 · Convenience sampling is a non-probability sampling method where units are selected for inclusion in the sample because they are the easiest for the researcher to access. This can be due to geographical proximity, availability at a given time, or willingness to participate in the research.
4. 抽樣與代表性 (Sampling and representativeness) 要明白抽樣的意思是什麼，必先辨別母群 (population) 和樣本 (sample) 兩個概念。 母群是探究的全體對像，樣 本則是通過特定抽樣程序所抽查之對象。 問題是，我們應以什麼準則抽取樣本？ 以上表為例，我們如何能確保所抽選的100名中學生能反映全港中學生對校規之看 法？ 來自不同年級、性別或成績組別的學生會否在這問題上有顯著的差別？ 來自不同階層和語言區域的新移民的歧視經驗又會否不同？ 持不同政治傾向的報章又會否 在報導上有系統性的分別？ 我們須在探究的最初階段盡量充實我們 對這方面的認識，在抽樣時採用適當的程序，以減低任何削弱代表性的可能。
2022年12月16日 · One of the non-probability sampling techniques is convenience sampling which is a way of selecting participants from the target population based on ease of access. This descriptive article aims...
Convenience sampling is a method of nonprobabilistic sampling that involves collecting samples from easily accessible locations or sources, such as computer science classes or online platforms like craigslist, to study specific phenomena like cyber-crime communication. AI generated definition based on: Research Methods for Cyber Security, 2017.
Convenience sampling (also known as grab sampling, accidental sampling, or opportunity sampling) is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand.
2023年7月31日 · Convenience sampling is a non-probability sampling method where data is collected from an easily accessible and available group of people. The individuals in the sample are selected not because they are most representative of the entire population, but because they are most easily accessible to the researcher.
Convenience sampling is the most common type of non-probability sampling, which focuses on gaining information from participants (the sample) who are ‘convenient’ for the researcher to access.
Convenience sampling is a non-probability sampling method where researchers use subjects who are easy to contact and obtain their participation. Researchers find participants in the most accessible places, and they impose no inclusion requirements. Convenience sampling is also known as opportunity or availability sampling.
任意抽樣 是 非概率抽樣 （英語：non-probability sampling） 的一種，以容易取得的資料作為 抽様 的 樣本 。 由於代表性不足，在科學上以任意抽樣為基礎的研究無法提供有關 母體 的資訊。 例如有人在某天早上在某一家店門口提供問卷請大家填寫，可以接觸到的人會受限在那個時間出現在那一家店的人，無法代表那附近人們的觀點，若問卷是一週幾天，每天幾個時段請大家填寫，會比較有代表性。 這類的抽樣常用在 先導實驗 中。 參考資料.
