About methodological standards for data collection

What is a methodological standard?

A methodological standard is a formal, agreed set of determining characteristics or benchmarks that describe the specific quality requirements for procedures and practice within a given context. Methodological standards seek to bring consistency to the ways work is done within Statistics New Zealand.

Why have methodological standards?

The use of methodological standards:

  • ensures best practice principles and guidelines in collection methodology are adhered to
  • ensures data is collected in a consistent and robust way
  • improves the validity and reliability of data
  • increases the efficiency when collecting data.

Benefits for data collection

Specific benefits of using methodological standards for data collection include:

  • increases quality assurance in the questionnaire development by reducing the non-sampling error and as a consequence, improve the accuracy of the data collected
  • supports the consistent and standardised design of data collection tools adhering to best practice
  • identifies and resolves questionnaire design problems and in so doing develop questionnaires that are easier to understand and easier to answer. This will reduce respondent and interviewer burden.
  • minimises the need for future redevelopment of questions by ensuring all questions are developed to a high quality
  • increases efficiency by reducing duplication of effort, and, risk of error from producing multiple documents that repeat information already recorded
  • ensures written communication to a respondent is consistent with corporate branding of Statistics New Zealand.
