What type of data is typically gathered through questionnaires and can be quantified?

The type of data that is typically gathered through questionnaires and can be quantified is quantitative data. This type of data is numerical and can be measured and analyzed statistically. Questionnaires often include closed-ended questions that allow respondents to select from predetermined answers or to provide numerical responses, making it easy to collect and analyze data in a structured manner.

Quantitative data is particularly valuable in research as it facilitates comparisons, identifies trends, and supports conclusions through statistical analysis. This type of data is distinct from qualitative data, which focuses more on descriptive information and subjective experiences rather than numerical values. By utilizing quantitative methods, researchers can easily aggregate results across a larger population to derive insights that have practical implications.
