Quantitative data is numerical data that can be analyzed using statistical techniques. Quantitative data is often collected through surveys, experiments, and the analysis of large datasets. Quantitative data can provide important insights into patterns and trends within a population or phenomenon. For example, a survey of customer satisfaction with a product or service can provide valuable quantitative data about the overall level of satisfaction among customers. In contrast to qualitative data, which is non-numerical and often analyzed through coding and content analysis, quantitative data is typically analyzed using statistical techniques, such as regression analysis or hypothesis testing. This allows researchers to identify relationships and trends within the data and to make inferences about the population from which the data was collected.

In UX (user experience) research, various quantitative data may be collected to understand user behavior and preferences. This can include data from surveys, experiments, and usability testing, as well as data from user analytics, such as website traffic data. For example, a UX researcher might survey to collect data from a large number of users about their experiences with a particular website or mobile app. The researcher could then use statistical analysis to identify common themes and trends in the responses and to develop recommendations for improving the user experience. In addition, a UX researcher might collect data from user analytics, such as website traffic data, to understand how users are interacting with a website or app and to identify areas for improvement. By collecting and analyzing this data, UX researchers can gain a better understanding of the user experience and can inform the design of digital products and services.
