What is a survey using a limited number of respondents and often employing less rigorous sampling techniques than are employed in large quantitative studies?

A survey using a limited number of respondents and less rigorous sampling techniques is often referred to as a qualitative or exploratory survey. These surveys typically aim to gather preliminary insights or opinions rather than generalizable data. They may utilize convenience sampling or other non-probability methods, focusing on depth of understanding over statistical validity. While they can provide valuable qualitative insights, the results should be interpreted with caution due to potential biases and limited representativeness.
