Reference table
Top tasks study sample sizes by goal
Recommended sample sizes for a top tasks study, by what you need the results for: a directional pilot, production prioritisation, a comparison across segments, or tracking over time with a yearly wave. Use it to size a study before you field it, and to explain to stakeholders why a pilot result is not yet a ranking to act on. Koji can field top tasks studies to your own customers or a recruited panel.
