1. Software/Tools For Running Web Experiments By Robert Slater Texas A&M -Corpus Christi

2. Considerations • Skills • Technology • Data Privacy • Features

3. Skills • What is your proficiency? • HTML, ASP, VB, JAVA, NONE • Hire external party • Do they understand what you are doing? • How important is their friendship? • Learn new skills? • learning curve.

4. Technology • What type of computer systems will access the software? • Windows XP, ME, 2000, 98, 95, 3.1, DOS, MAC • Will the code you have work on the different operating systems or web browsers? • Do you have a web-server you can use to host your study? • Would a third party notify you in advance of server maintenance?

5. Data Privacy • Where will the data be stored and who will have access to it? • If you use a third party hosting site can you keep your data confidential? • Can you control backup copies of your data?

6. Features • What kind of features do you need in your study? • I needed: • Randomization into treatment groups • Piping with mathematical manipulation • Multiple Question formats • Data Export • Customization • User sign in options (specific/anonymous) • Java script capability within survey pages

7. My Solution • Adapted an open source survey software to meet experimental needs (www.ClassApps.com) • ASP based open source software • Multiple database support – • Supports data export to excel • Professional looking finished product • No programming experience needed • Quick learning curve

16. Limitations and Solutions • Software not designed for multiple treatments: • Create multiple questionnaires based on treatment groups • Created one master survey and copied it to create separate treatments • Software would not randomize subjects: • Use separate web page and basic java script to randomize subjects into treatment groups • Software allowed hyperlinks to surveys

17. Multiple Treatments

18. Limitations and Solutions (cont) • Software allowed for piping but not mathematical manipulation as needed in my study. • I needed to be able to: • Take users estimate of Earnings Per Share • Give them management’s estimate that was calculated as a percentage of user’s response.

19. Piping • Take data input by participants and use in the study. • Personalize questions • To develop rankings using data input by users.

24. Piping Solution • Program already allowed for piped responses. • Open source software allowed me to manipulate the ASP source code to perform mathematical function on piped response.

30. Conclusions • Quick learning curve. Little expertise necessary. • Customizable software allowed for unique functionality. • Locally housed database on web server allowed for data privacy and further customized data gathering. (Timed responses) • Customized programming problems led to incompatibility with some operating systems. • Participants were dropped from the study before completion.
