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 institutions provided estimates due to a lack of separately recorded data on R&D activity.
    • Data were self-classified by institutions to Type of Activity, Fields of Research and Socio-economic Objective at the time of reporting. Some institutions 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 institutions and reference periods.

REVISIONS

4 In the event of new information being identified and revisions made, revised figures will be indicated by a footnote. Revisions must be taken into consideration when interpreting results, particularly when comparing estimates over time.
