The Quality Declaration expresses the basic ideas and commitments of the President and top management of the SOSR for the Quality Policy as well as increasing efficiency and effectiveness of the integrated management system of the SOSR. Quality policy is based on the mission of the Statistical Office of the Slovak Republic: to provide high quality and objective statistical products and services by keeping confidentiality of statistical data and by minimising burden on interested parties using effectively existing resources with the aim to support improvement of the information and intellectual capital of our customers. In this way we want to contribute to reduce risks and improve effectiveness in their decision making processes and so to support the sustainable development of the Slovak Republic as the part of EU. The Quality manual describes the documented procedures of the quality system that are used for implementation and continuous improvement of the quality management system in SOSR. It contains a description of the quality management system and the fulfilment of requirements ISO 9001 standards. Application of the manual in practice ensures that all activities that have an impact on the quality of the products created are planned, managed, reviewed, evaluated and meet requirements. Quality manual is available only in Slovak language. The European Statistics Code of Practice is the basis of the common quality framework of the European Statistical System. It is a self-regulatory tool and it is based on 16 Principles covering the institutional environment, statistical processes and statistical outputs. A set of indicators of best practices and standards for each of the Principles provides guidelines and benchmarks for reviewing the implementation of the Code of Practice, thus increasing transparency within the European Statistical System. |
|||
11.2. Quality management - assessment | |||
Coverage, reference period, data collection, control and data processing are in line with the Eurostat methodological guidelines. The data collection process is conducted in the Integrated Statistical Information System called ISIS.

The data collection process is ensured by the regional offices of the SOSR during the phase of electronic data collection, ensure using statistical controls and algorithms the data collection process itself. Data validation is done during the data collection, processing and validation of relevant data by the SOSR experts. A data comparison is done with previous periods. Statistics are available in the system to evaluate the quality of the completed questionnaires, the number of questionnaires with errors or outliers, the number of reminders etc. SOSR also performs internal methodical audits. Evaluation of statistical surveys and methodological audits including the analysis of the results are integrated into the existing quality management system. STS compliance assessment is carried out by Eurostat. Concerning the results of particular data production processes, the overall quality of the indicators is considered to be as good. |
|
|||
12.1. Relevance - User Needs | |||
The requirement to conduct consultations with users of statistical information is stipulated in the Act on State Statistics itself. Consultations during the preparation of state statistical surveys take place within the framework of the preparation of the Program of State Statistical Surveys (PSSZ). PSSZ is a generally binding legal regulation compiled by the SOSR in collaboration with ministries, other central authorities and state organizations and contains statistical surveys organized and carried out by the SOSR, ministries, other central authorities and state organizations. SOSR publishes the Programme of State Statistical Surveys by decree in the Collection of Laws of the Slovak Republic. The Coordinating Council for State Statistics ensures the fulfilment of the tasks of the SOSR. Key users of specific statistical products are listed in the Marketing Plan, e.g. international organizations - Eurostat, OECD, UN and national institutions, e.g. National Bank of Slovakia, etc. |
|||
12.2. Relevance - User Satisfaction | |||
Since the 2009, SOSR carries out satisfaction surveys of customers with their products and services at two-year intervals. The goal of surveys is to determine customer satisfaction with the products and services of the SOSR, to obtain information about users, their interest and opinion on provision and quality of statistical products and services. The facts obtained are a valuable resource for the direction of other activities of the SOSR. The goal of the SOSR until 2022 is to systematically increase the value of the institution and its recognition at the national and international level. The office also monitors the fulfilment of the stated goal with the help of indicators of the credibility of the SOSR and the rate of use of the information provided by the public. SOSR conducts credibility surveys through an external independent organization once every 2 years, with the intention of ensuring the objectivity and indisputability of the results from public view (available only in Slovak language). |
|||
12.3. Completeness | |||
Time series of import price indices in accordance with the regulation are available since January 2009 (date of entry of Slovak Republic into euro area). |
|
|||
13.1. Accuracy - overall | |||
Overall accuracy is considered very good. SOSR makes great efforts to prevent the occurrence of errors in the data and performs data verification to detect the errors. Most errors are directly consulted at regional offices with the reporting units. |
|||
13.2. Sampling error | |||
Sampling errors are monitored during data processing. |
|||
13.3. Non-sampling error | |||
The technical project of data processing is part of ISIS. This project includes a description of all logical data controls at the microdata level performed during electronic data collection. The electronic questionnaire and information system ISIS itself provides many arithmetic and logical checks between variables, which we distinguish between serious and informative. Data collection is provided by the regional office of the SOSR in Trenčín. After the deadline for submission of the statistical questionnaire, the reporting units that did not respond are contacted again to fulfil their legal obligation. In case of serious errors in the form, this form is not accepted and with the help of experts from the regional office its correctness is ensured so that it can enter into the data processing. Automatic validation checks during data collection and informative checks are incorporated with the aim to follow logical checks, reducing the rate of partial non-responses, anomalies and outliers. The purpose of this process is to minimize errors already in the data collection itself and subsequently during data processing. The basic step in the process of calculating unit non-response is the analysis of the population with regard to the state of activity of the reporting units. For this purpose, we use a specific classification of responses and non-responses codes. Individual codes describe active and inactive units and are assigned to each reporting unit. Subsequently, we determine the population of active units entering the data processing. Response rate for September 2022 was 0,984375. |
|
|||

|||
15.3. Coherence - cross domain | |||
The following data comparison analysis is done:
The analysis shows very good compliance level in case of parts of population surveyed exhaustively. Some differences appear when comparing data from monthly, quarterly and yearly samples, which are the subject of further detailed data analysis. |
|||
15.4. Coherence - internal | |||
There are no problems with internal consistency in case of import price indices. |
|
|||
SOSR regularly monitors the cost and burden of reporting units. As part of the optimization of statistical surveys, it takes measures aimed at reducing their burden (e.g. by personalised pre-filling of selected variables in statistical questionnaires, reducing the frequency of selected surveyed variables and using administrative data resources if they are available in the required quality and at the specified time). The cost and burden measurement at the level of European Statistical Products is in competence of the Resources Directors Group within Eurostat. |
|
|||

Data are not subject of revisions. Mean Revision (MR) = Mean Absolute Revision (MAR) = 0. |
|
|||
18.1. Source data | |||
The import price indices are calculated based on prices, which are reported through statistical forms named "Monthly questionnaire on prices in foreign trade for import and arrival of goods“. These forms are filled-in by selected reporting units for selected representatives. In year 2022 there were approximately 1010 selected representative commodities monthly reported by approximately 255 reporting units. |
|||
18.2. Frequency of data collection | |||
Data are collected monthly. |
|||
18.3. Data collection | |||
The regional office of the SOSR in Trenčín is responsible for data collection. Since the 1st of January 2016, reporting units (legal entities, natural persons - entrepreneurs) are required to electronically submit statistical questionnaires in accordance with the amendment to Act No. 540/2001 Coll. on state statistics as amended by Act no. 326/2014 Coll. (hereinafter referred to as the law), which contains new rules for submitting statistical questionnaires. The completed statistical questionnaire must be submitted electronically no later than the 20th day after the reference period on the website www.statistics.sk. In the event that the reporting unit has not submitted the electronic questionnaire, it is contacted by the relevant regional office of SOSR. Data collection is closed cca 30 days after the end of the reference month. |
|||
18.4. Data validation | |||
The data entry, data completeness and statistical control are organised by specialised regional offices of the SO SR. SOSR distinguishes between two levels of data checks:
According to the importance there are classified 2 basic types of checks:
Most of the errors are directly consulted with the reporting units by our regional offices. |
|||
18.5. Data compilation | |||
Import price indices are calculated from simple price indices of particular representatives weighted by the relative share of the relevant representative in the total import for year 2015 (stable weight structure) in accordance to the Laspeyres formula. The weights of import price indices are based on the structure of import of goods of the Slovak Republic for year 2015 and the single-shot survey focused on the selection of representatives for price monitoring in the foreign trade for year 2015. Non-response is treated by the imputation of data from the previous month’s survey. |
|||
18.6. Adjustment | |||
Import price indices are neither working day nor seasonally adjusted. |
