What type of research is typically used in user trials and testing?

User trials and testing typically require both qualitative and quantitative research to provide a comprehensive understanding of user experiences and product performance.

Quantitative research aids in obtaining measurable data, as it allows researchers to gather numerical information about how many users prefer a specific feature, or how often a product fails during testing. This statistical data can be collected through surveys, questionnaires, or performance metrics, providing a solid basis for evaluating various aspects of the product.

On the other hand, qualitative research offers insights into the user experience that numbers alone can't capture. During user trials, qualitative methods, such as interviews and observational studies, help in understanding user behaviors, feelings, and interactions with the product. This can reveal why users feel a certain way about a product or which features they find intuitive or confusing.

Combining both types of research gives a richer perspective, enabling designers and engineers to not only measure how well a product performs quantitatively but also to understand the user experience qualitatively, leading to more informed decision-making in the design process.
