ABSTRACT
Quantitative UX research methods collect numerical data that can be analyzed quickly to generate generalizable findings or benchmarking metrics. Several quantitative metrics can be captured to evaluate usability, such as time on task or the number of errors a user makes as they are interacting with a HIT. The quantitative data collected right before or after a HIT has been implemented are typically intended to validate the design or ensure that the product is usable for the target audience. The UX research that occurs at the end of the full system development lifecycle is called summative research.
