Advanced Web Surveys - offer many exciting advantages over
the pre-packaged products available on the web. Our internet survey sofware was developed
in-house and is a proprietary system. Most online survey packages can play multimedia files,
show images and offer simple logic for question skip patterns and forward piping of answers,
as does ours. But when you need to conduct a research survey that requires compund sample quotas,
balanced sample versioning for low-incidence, random sample with augment sample fulfillment,
overlapping non-mutually exclusive groups, random page display, conjoint, discrete choice,
Max/Diff scaling, timed media display, real-time segmentation or other complex techniques
then you need an advanced web survey. DVR West can design, program and host a survey that
will meet your needs.
