在一项有123名参与者参与的研究中，对五份用于评估网站可用性的问卷进行了比较。所研究的问卷是SUS、QUIS、CSUQ，这是微软产品反应卡的一个变体，我们在可用性实验室中已经使用了几年。每个参与者在两个网站上各完成了两项任务：finance.yahoo.com和kiplinger.com。所有五份问卷都显示，一个网站明显比另一个网站更受欢迎。对数据进行了分析，以确定在6到14个不同样本量的情况下，结果会是什么。在样本量为6的情况下，只有30%-40%的样本会确定其中一个地点是明显优先的。大多数数据在样本量为12时达到明显的渐近线，其中两份问卷(SUS和CSUQ)至少有90%的时间得出与完整数据集相同的结论。
Five questionnaires for assessing the usability of a website were compared in a study with 123 participants. The questionnaires studied were SUS, QUIS, CSUQ, a variant of Microsoft’s Product Reaction Cards, and one that we have used in our Usability Lab for several years. Each participant performed two tasks on each of two websites: finance.yahoo.com and kiplinger.com. All five questionnaires revealed that one site was significantly preferred over the other. The data were analyzed to determine what the results would have been at different sample sizes from 6 to 14. At a sample size of 6, only 30-40% of the samples would have identified that one of the sites was significantly preferred. Most of the data reach an apparent asymptote at a sample size of 12, where two of the questionnaires (SUS and CSUQ) yielded the same conclusion as the full dataset at least 90% of the time.
