Matrix is experienced in all survey research methodologies, but we utilize the telephone survey most frequently. State-of-the-art technology through computer assisted telephone interviewing (CATI) provides our clients the best available option today for speed, efficiency and technical accuracy. Our current capacity is 300 individual interviewer stations.

Are Most Effective When:

• Statistical reliability and scientifically projectable findings will be key factors in the how the research is used.


• Representative cross-sections of a greater market must be surveyed.


• Results are needed quickly.


• Question patterns are complex or require custom follow up questions beyond ordinary "skip" patterns.


• Questions must be asked in a prescribed sequence, such as unaided and aided awareness.


• Sample lists are limited and may require multiple call-backs, or even scheduled appointments to reach specific respondents.


• Multiple or complex sample quotas or respondent screening qualifications are required.

Features That Make It Work:

• Question sequence and skip patterns are programmed and automated.


• Sampling randomization and quota procedures are electronically managed.


• Survey questions are displayed on an interviewer's monitor screen for precise reading to respondents.


• Answers are recorded by keyboard and continuously compiled.

Quality Control:

• Matrix clients have the option of listening in real time to actual interviewing. Monitoring is useful for pre-testing questions or simply for a demonstration of interviewer performance.


• Because CATI is electronically-based, high-speed data transfers allow daily reporting of results.


• Interview stations are staffed by formally-trained, experienced, professional telephone interviewers.
