Random Number Generation

Symphony Research uses a method of random sample generation. Our selection procedure ensures equal probability selection and proper sample representation of listed and unlisted households.

In addition for hard-to-reach targets and in particular low incidences, we have the capability to blend sample sources from a number of different area’s decreasing project costs.

This could include panel and telephone lists or social networking sample sources.

B2B Sample Sources

We use a number of different suppliers who are experts in their collective fields.

We are totally unbiased in selecting who we use and base this selection on experience, size of lists and scope of the provider.

Symphony is a preferred supplier of the largest list brokers in New Zealand & Australia and as such can provide volume discounts.

Random Selection.

This permits justifiable inference from the sample to the population, at quantified levels of precision. Random selection also helps guard against sample bias in a way that selecting by judgement or convenience cannot.

Sample selection and quota structure is based on the latest census figures.

Call Management

Our powerful SMS (sample management system) controls sample management and placement of calls and implements a structured call-back regime that can be modified to suit individual client’s needs. The scheduling algorithm ensures that sample items are not discarded until they have been thoroughly worked and manages appointment dates and times. In the project set up we dictate the number of call-backs to be made to a household before we stop making call backs to the number. No answered numbers are not called back for at least 3 hours and engaged numbers are not called back for at least 30 minutes. 5 attempts are made to each household at different times on different days before substitution is allowed.
