Abstract
Official statistics refer to public information which is produced for the benefit
of the society and is funded by the state budget under the official or statistical
1
programme. Also, in GSBPM , quality of official statistics producing by
statistical agencies has been highlighted significantly. Despite the fact that
data quality framework has different dimensions comprising relevancy,
timeliness and punctuality, coherence and comparability, accessibility and
clarity, this paper focused on accuracy and reliability aspect. Additionally, a
specific case study on manufacturing establishments’ statistics in Iran was
expanded. Due to its importance, providing consistent, reliable and high
accuracy data has been one of the prominent targets of these sector. In order
to improve this data quality aspect in these case, a practical software was
proposed to help statisticians and experts in NSOs . Although there are a
2
range of causes and factors that are significant in improving the reliability and
accuracy of data from data gathering to publishing, the proposed software
focus on the Editing and imputation stage in this process, specially macro
editing. Presumably, quality of the gathered data from the surveys or
establishments directly are just affected by technical editing in the process and
other pre-editing stages have trivial impact and not completely controllable
and improvable based on experts’ opinions. Additionally, this software can
obviate the data non-consistency by providing multi-dimensional insights and
comparable data of each establishment. In this comprehensive overview
3
different dimensions of growth e.g. ISIC activity field, provincial and sub-
provincial cutting level etc. was reflected. Remarkably, financial statements as
secondary register-based data source in this process either to make
comparison or replacement with survey data will promote the accuracy was
considered is this software. These registered data source are available free in
stock market websites or received physically from Audit organizations. This
study also can help other statistical agencies to produce higher quality
statistics indifference the kind of activity or where they are located.
