can give you insights into your users that will help you come up with better ideas that are more likely to be valid because they’re based on something.
is a method of finding out whether something is valid, like a design concept, marketing copy, a prototype, or a hypothesis. With evaluative research, you’ve already come up with a hypothesis or idea or even a product, and you’re testing it to see what’s right or wrong about it.
What or Why
is happening with your users is all about quantitative data
is happening it's about behaviour and qualitative data
