A Comparison of Questionaires Thomas S. Tullis & Jacqueline N. Stetson UPA 2004 funded by Fidelity Investments Variety of questions have been reported in the literature for assessing percieved usability. Worrys about effectiveness of these questions was the reason for this study. Quesionaires used were: 1. System Usability Scale(SUS) 2. Questionaire for User Interface Satisfaction 3. Computer System Usability Questionaire 4. Words 5. Fidelity Investments own questionaire The study was carried out online on fidelity investments intranet 123 participants. Two sites used were: 1. finance.yahoo.com 2. kiplinger.com The users were asked to carry out to tasks. 1. Find the highest price in the past year for a share. 2. Find mutual fund with the highest 3 year return. Overall score was generated by converting each questionaires score to a percentage. All 5 showed site 1 to score higher. Although the accuracy of the results would have been better with a larger dataset. Also only two sites and two tasks gave limited results. It is also easier to compare to sites to each other than it is to evaluate a stand alone website. I found this paper a little limited in the the depth it went into the subject.
