The legal basis of the quality measurement and assessment is the internal Regulation of Statistics Poland's President No. 35 of 28th December 2011 which came into force in the 4th quarter of 2012. The quality assessment of statistical surveys was conducted according to an annual quality program for the official statistics which was in line with the Regulation of the Statistics Poland's President No. 35 of 28th December 2011. Procedures and rules applied in quality assessment and monitoring are based on the ESS Quality Standard, i.e. the European Statistics Code of Practice (CoP). |
|||
11.2. Quality management - assessment | |||
The quality of statistical surveys is assessed by means of standard quality reports and quality indicators recommended in the ESS Handbook for Quality Reports with further amended versions as well as by self-assessment checklist and quality audits and reviews. The price indices for the surveyed month on the level of enterprises are analysed taking into consideration the price indices of construction and assembly works going beyond the scope (80%-110%). The aim of this analysis is to confirm a real movement of price construction and assembly works (a drop or a growth) or to detect incorrect calculation of the index due to errors reported in the questionnaire. When an error is detected, an impact of this error on the index of an enterprise is analysed. If an error causes a change of an index by 1.0 percentage point, the index is corrected starting from the representative level. In the following step, the price index for the enterprise, which reported incorrect data, is calculated. If significant errors within price levels of the representative are found, after closing the survey for reporting month, a reporting unit makes correction of data in the following month by inserting correct data into appropriate line of the questionnaire. |
|
|||
12.1. Relevance - User Needs | |||

Notice about minor changes is given at the time the change is introduced. |
|||
17.2. Data revision - practice | |||
Data changed in relation to the first released are disseminated with a comment. Data revisions are sporadic. |
|
|||
18.1. Source data | |||
The source of data is statistical survey covering economic entities employing 10 or more persons. An essential criterion for selection is the annual value of sold production of economic entities employing 10 and more persons and necessity of ensuring representation in every NACE group. The list of entities is next verified by regional statistical office and supplemented with entities which are important at the voivodship (NUTS 2) level whereas entities, which production is less important or which are reluctant to provide information, are removed from the list. Due to continuous changes in the field of construction activity (liquidation, fusions, creation of new entities, changes in the structure of carried out works), the list of surveyed entities is updated annually. Reporting units selected for the survey choose representatives of construction and assembly works, which are carried out in the reporting month. Selection of groups of works and their representatives is purposive and based on the strictly definite criteria included in the explanatory notes of the C-01b questionnaire. In the first place, the reporting unit chooses groups of works, which together amount to at least 70% of the value of works conducted by the enterprise in the area of country. Then the reporting unit from selected groups chooses sub-groups, which the total sum amounts to at least 60% of the value of this groups of works. Within the chosen sub-groups, the reporting unit chooses representatives of works which are the most often carried out and which have the greatest share in the value. Each sub-groups of works should be represented by at least 3 works. |
|||

|||
18.5. Data compilation | |||
Weighting system is based on:
For each group of buildings the model of cost estimates is created. On this basis the share of individual types of works in building is calculated.
|
|||
18.6. Adjustment | |||
Seasonal and calendar adjustment procedures are not applied. |
|
|||
Not applicable. |
