2. Understand Descriptions in the Catalogue

Publication Year: 08. 04. 2017    Date of last inspection: 08. 04. 2017

 

Adequate information about the study content and context are vital for the understanding of the research data. Each study in the Catalogue of the ADP includes appropriate metadata. Metadata are all information needed for understanding and processing of the statistic structures.

 Before analyzing the data, read all the available documentation about the study carefully. Note that without a thorough understanding of the study background and its implementation process, the interpretation of the data/analysis may be false!

 

Studies in the Catalogue of the ADP are described in a uniform way, using the elements of the international specification DDI-C, composed from five main fields: description of the document, description of the study, description of the data, description of variables and accompanying materials.

Studies in the Catalogue of the ADP can be browsed in two ways, namely on the web page of the ADP and on the Nesstar Browser. The descriptions of the studies are the same in both ways, however, the presentation of the descriptions are different (see tabs Web Descriptions and Nesstar Descriptions).

All study descriptions and accompanying materials are freely accessible, therefore a prior registration is not needed to access them.

The web page view of the Catalogue of the ADP  is intended for searching studies and examining study descriptions, descriptions of data and accompanying materials. Each study description is equipped with a link to the Nesstar browser page of the study (if a study is available also on the Nesstar browser).

The Nesstar browser enables searching, browsing of studies, online analysis of data and data download. Most of the studies that are present in the Catalogue of the ADP on the web page of ADP is also present on the Nesstar browser, except for studies that have either only a partial study description or are lacking documentation or do not have data etc. Research data from the Nesstar browser are usually possible to analyze online or download locally – for both options a prior registration is required.

In the Catalogue of the ADP on the web page, each study is divided into 4 sections. Example:

Opis splet

 

  • Study Description: basic description of the study (authors, keywords, topic fields) and methodological information (collection date, geographic coverage, universe, sampling procedure etc.).
  • Data Description: information on the data file and frequencies of distribution of individual variables in the data file, together with question texts and answers.
  • Accompanying materials (for example questionnaire and various publications).
  • Nesstar Browser (link to the study on the Nesstar browser where there is a possibility to download the full study description and/or data file – not available for all studies in the Catalogue of the ADP).

 

Information in the right sidebar additionally inform about:

  1. Terms of Access: determined by our policy of access (see tab General Terms of Use in the Section 1. Read the Terms of Use). Most of the studies is available under the CC-BY licence.

a) Description of Buttons

 

b) Study Description

On Nesstar Browser you can see study descriptions and analyses of research data in three different tabs, namely Description, Tabulation and Analysis.

Nesstar prikaz

 

Study Description, together with frequencies distribution, is possible to see in the tab Description. In the tab Tabulation, you can see a one or more dimensional analysis of selected variables. The tab Analysis enables the possibility to calculate the Pearson correlation coefficient and do linear regressions.

By clicking on the plus sign in the section Metadata and Variable Description you can access individual subfields of the study description. This is the same description as found on the web page of the ADP, however, the description is more detailed.  

Podrubrike Nesstar

 

Full Study Description is visible on the right hand side, when Metadata is clicked.

 Attention: When a data file is not accessible(for example in international studies, where the ADP does not distribute data), the tabs Tabulation and Analysis are not active!

 

c) Variable Description

Variables can be found in the section Variable Description. By clicking the plus sign we can open the list of variables that are found in the data file. The list is divided according to topics, found in the questionnaire.
