🌱 Quantitative vs Qualitative tests
Qualitative usability testing aims to identify issues in an interface, while quantitative usability testing is meant to provide metrics that capture the behavior of your whole user population.
qualitative user studies are mostly formative: their goal is to figure out what doesn’t work in a design, fix it, and then move on with a new, better version.
To make an analogy for this assumption: if one person falls into a pothole, you know you need to fix it. You don’t need 100 people to fall into it to decide it needs fixing.
