On-line Experimenting, from planning stage to log file analysis: Basic concepts, software, techniques, and insider tricks

2.) duration of the workshop:
two times 90 minutes

3.) workshop fees:
65 Euro/ 35 Euro

4.) target groups:
Researchers and employees of companies who would like to conduct Internet-based experiments and/or analyses of log files. The workshop is useful for both newcomers and experienced experimenters. It will contain information about the newest developments.

International workshop, mostly held in English. Individual coaching during practice parts will also be available in German.

6.) workshop language:

7.) Description of the content of the workshop:
This workshop will provide you with an up-to-date overview of basics, techniques, methods, tricks, and tools for Internet-based experimentation. You will learn about ways of dealing with issues in experimental design, security, recruitment, sampling, self-selection, multiple submissions, question design, dropout, error estimation, distributed experimentation, data handling, data quality, and log file analysis. Among other "tricks", you will know the high hurdle technique, the warm-up technique, sub-sampling procedures, multiple site entry, and ways to check for motivational confounding. Using a practical example, you will learn how to conduct Web experiments within hours. For this purpose, the workshop includes a hands-on demonstration of interactive systems for designing Web experiments online, e.g. WEXTOR ( You will learn how to make use of Web services like the free "::web experiment list::", and of analysis tools for subsequent data analysis, such as Scientific LogAnalyzer. Additional information materials will be provided, Workshop participants will receive free temporary licenses for WEXTOR and Scientific LogAnalyzer.

8.) goals of the workshop:
Learn or review basic knowledge about Internet-based experimenting; learn a number of useful techniques and tricks; learn to avoid pitfalls that may make your experiment useless; create an experiment during the workshop; get to know several tools and how to use them.

9.) necessary previous knowledge:
How to use a Web browser.
