(btw: a great and easy argument!). how many persons do you test by asking 10 cases? i assume you need a high enough number of test persons to have significant and reliable findings.</p> <p>if you want to have a comparison between the old structure and a new one, do you choose the same persons? i think you need different groups of test persons, because the first tested group remembers the ols structure and this would falsify the findings&#8230;</p> <p>how much time do you spend in finding test persons that are part of the defined target group? we often use colleague for &#8220;discounter testing&#8221;.</p> <p>cheers,<br />rene</p> http://www.boxesandarrows.com/view/tree-testing#content_49480 http://www.boxesandarrows.com/view/tree-testing#content_49480 Fri, 25 Dec 2009 18:42:25 GMT Rene Welter
