The use of appropriate and efficient survey design and collection methods underpins the survey-taking process at Statistics New Zealand. By using internationally accepted and up-to-date methods, sources of survey error can be reduced. This is both sampling error (the error that results from taking a sample rather than using information from the whole population) and non-sampling error (for example, relating to frame imperfections, imprecise objectives, poor question design and non-response).
At Statistics New Zealand, an important aim of our ongoing work is to understand, manage, control and report on all known sources of error that impact on the quality of our statistics. It is not possible to eliminate all sources of error. However, our continued efforts at understanding and managing variability and error ensure we are exercising a high level of control on all known sources of error through the targeting of resources to control the errors efficiently and effectively. The design of our collections is based on the resulting statistics being reliable enough to support the main uses of the data. More demanding users of the data need to take into account the various likely sources of error which could impact on that use. The non-sampling error webpages aim to provide information about the various sources of non-sampling error to allow users to make some informed judgement about the use of statistics produced from Statistics New Zealand's economic surveys.
This section provides information on the survey design and collection methods used by Statistics New Zealand.
