Quizplus · Accepted Answer

Haphazard selection is a sample selection method that is done randomly or by chance, without any systematic approach. In this method, the researcher may choose items that appear convenient, accessible, or interesting, without any deliberate or pre-determined pattern. This method is also called random sampling without replacement, as each new item is chosen independently of the previous ones. The main advantage of haphazard selection is that it can provide a representative and unbiased sample if the items are chosen from a population that is sufficiently large and diverse. However, this method may be subject to bias if the researcher unconsciously or deliberately selects items that are not typical or relevant to the research question.
