Why a study with only 7 respondents can be good – from Dutch paper “De Volkskrant”

Posted by jpluimers on 2021/01/07

[Archive.is] Waarom een onderzoek met maar 7 respondenten toch goed kan zijn | De Volkskrant: Denkfouten in het hedendaags ontwerp gefileerd door innovatie-expert (en cabaretier) Jasper van Kuijk. Deze week: gebruikstest.

Google translated in English.

TL;DR

Quantitative studies often require large numbers of respondents, but quantitative studies can be done with a very small group.

While quantitative studies often will get you just one result (I rate this application a 7 out of 10, or with this A/B change, click through increases by 5%), qualitative studies will get you much more specific comments like “the main menu is cluttered”, or “the design is slick” (translated from the Image in the article).

Extensive research was done for a 2003 published paper [Archive.is] Beyond the five-user assumption: Benefits of increased sample sizes in usability testing which you can read as PDF [WayBack].
