Sentenium has developed and honed advanced procedures that ensure data quality, integrity, and accuracy throughout the course of our clients' research projects. Everything we do allows us to keep up with evolving market research industry standards.

Our proprietary tracking technology, STracker, ensures that every document or survey we process is "visible" and accounted for through every stage of processing. With a unique code, we can track every document or survey and every single data file connected to that document or survey. This is especially relevant when dealing with relational databases (such as Microsoft Access, Quattro, mySQL, and Oracle), since, by definition, such databases link multiple data files to each other.

 
At our clients' request and/or our recommendation, we also perform additional validation techniques such as:

        Data / Range checks: We use these checks to identify invalid data,
         such as data that is not within a stated or logical range.

        Double verification: We have separate people manually enter data into a system. Both sets of data
         are compared against the original documents received.

        Duplicate case checks: We find and correct situations where, for example, one individual has multiple
         identification numbers. This is especially relevant when working with relational databases.
