TECHNICAL NOTE DATA QUALITY


NON-SAMPLING ERROR

1 Non-sampling errors may arise as a result of errors in the reporting, recording or processing of data. These errors can be introduced through inadequacies in the questionnaire, treatment of non-response, inaccurate reporting by data providers, errors in the application of survey procedures, incorrect recording of answers and errors in data capture and processing.

2 The extent to which non-sampling error affects the results is difficult to measure. Every effort is made to minimise non-sampling error by careful design and testing of the collection instrument, the use of efficient operating procedures and systems, and the use of appropriate methodologies.

3 When interpreting the statistics in this release, the reliability and comparability of the estimates may be affected by the following specific non-sampling errors:

  • Many organisations provided estimates due to a lack of separately recorded data on R&D activity. This was most prevalent for government organisations without a specific research focus.
  • Data were self-classified by organisations to type of activity, fields of research and socio-economic objective at the time of reporting. Some organisations may have experienced difficulty in classifying their R&D projects. The ABS makes every effort to ensure correct and consistent interpretation and reporting of these data by applying consistent processing methodologies.
  • The estimation method for R&D related overhead costs varied across organisations and reference periods.


REVISIONS

4 Revisions to previous cycle data occur on discovery of:
  • errors in reported data, typically a result of the specific non-sampling errors outlined in the Non-Sampling Error section above; and
  • newly identified R&D performers who indicated they had significant levels of R&D in earlier years (details are collected and used to revise previously released estimates).

5 Revisions are applied one cycle prior to the current cycle, but only where the impact on:
  • R&D expenditure is equal to $5 million or more; or
  • Human resources devoted to R&D is equal to 25 PYE or more.

6 Where new information was identified, revisions were applied to 2011-12 estimates. Revisions must be taken into consideration when interpreting results, particularly when comparing estimates over time.
