About Dieter

Are you looking for support with market research projects or data analysis?
- to bridge bottlenecks
- also gladly with a long-term perspective

I am a self-employed market researcher with many years of experience in institutes, companies, and projects. I have been a freelancer since 2007 and support institutes/companies in quantitative market research and data analysis.

My service spectrum covers the entire market research process. I am used to carrying out studies/projects as an external project manager, but I also frequently take on partial tasks such as data analysis with SPSS, questionnaire development/programming, creating reports/charts with PowerPoint, etc.

A focus of my work is data analysis, multivariate methods, segmentation, conjoint analysis, etc.

Due to my experience, I quickly know what is important, cover a broad spectrum of methods, and bring in my know-how from numerous industries/institutes.
