Quality Assurance

Symmetric Tabulation Programmers use a strict multi-step check list when creating the cross-tabulations. Each programmer's logic is double-checked by a second programmer and then final tables are checked by the Quality Assurance Department for a thorough review.

Advanced Statistical Analyses

Many different types of mathematical tests and analyses can be conducted on the data by using SAS, SPSS, and R-Language, such as:

Correlation analysis
Cluster analysis
Factor analysis
Multiple regression
Discrete modeling, choice modeling
Market segmentation

Questionnaire Design and Guidance. Symmetric provides assistance with questionnaire design before data collection begins. This is especially important for studies requiring market segmentation, choice modeling, or other advanced statistical techniques.
