Which method is commonly associated with quantitative data?

Surveys with closed-ended questions are widely recognized for their ability to generate quantitative data. This method involves structured questions that provide respondents with predefined response options, such as multiple-choice answers or rating scales. The responses can be easily quantified, allowing researchers to perform statistical analyses and draw conclusions based on numerical data.

Quantitative data typically involves measurable quantities and statistical analysis, which is precisely what closed-ended surveys facilitate. They produce clear, comparable data that can be aggregated and analyzed across a larger population, making it easier to identify trends, correlations, and overall patterns.

In contrast, interviews with open-ended questions and focus groups that discuss experiences primarily generate qualitative data. These methods focus on in-depth understanding and personal insights, rather than numerical data, making it challenging to quantify responses. Similarly, case studies offer detailed qualitative insights into specific instances or phenomena, lacking the broad statistical applicability found with closed-ended surveys.
