The questions you should ask with qual and quant data in UX content research
Qualitative (Qual) Data:
Subjective information can be hard to represent in numbers. Measuring user’s feelings and opinions about the qualities of a product. This “data” comes from focus groups, interviews.
Quantitative (Quant) Data:
Metrics that can be counted and measured in numbers or values. How many clicked? How many filled out a form? “Hard” data, measureable actions.
In general, your research should seek to answer some (or all) of these questions:
Qualitative
How do users feel about the brand promises?
How do users feel about the product value proposition?
How would users would describe the qualities of your feature, product, or brand?
How would users describe your product voice? (Does it match what you intended?)
Do users respond well to contextual terms used throughout the UI?
Do users see themselves in the terms used to describe them?
Quantitative
What percentage of users are successfully completing tasks?
What percentage of users enter the sales funnel and make it all the way to a purchase?
What percentage of users successfully make it past transition points, like clicking from a landing page to a checkout flow, or from your onboarding screens to your first task flow?
