7. MICS Data Processing System Designed to deliver the first results of a survey within several weeks after the end of fieldwork simultaneouslySuch rapid turnaround time is possible when completed questionnaires are entered simultaneously with survey fieldwork all the questionnaires from a clusterData for each cluster is stored in a separate data file and is processed as soon as all the questionnaires from a cluster are returned from the field This approach breaks data processing down into discrete segments and allows it to progress while fieldwork is ongoing By the time the last questionnaires are finished and returned to headquarters, most of the data have already been processed

8. Primary Data Processing Flow Main Data Entry Structure Check Verification Data Entry Difference Listing Backup Raw Data Secondary Editing Backup Final Data

9. Primary Data Processing Main data entry –First time data is entered Structure check –Checks structure of data files Verification data entry –Second time data is entered Difference listing –Two data files are compared; differences resolved

10. Primary Data Processing Raw data backup –Verified data are backed up to a directory containing raw data files Secondary editing –Complex inconsistencies are investigated and resolved if able Final data backup –Edited data are backed up to a directory containing edited data files

11. Data Processing Personnel Questionnaire administrators Data entry operators Secondary editors Data processing supervisor

12. Questionnaire Administrators Receive clusters from the field Check that all questionnaires are present Check that questionnaires are ready to enter Check that HH and individual questionnaires are in the proper order, and rearranges them if not Keep track of location of all clusters Should follow interviewer training

13. Data Entry Operators Enter main data Enter verification data Resolve differences between files Must follow interviewer training Must be familiar with the questionnaires

14. Secondary Editors Investigate complex inconsistencies Tell supervisor if and how to resolve inconsistencies Review editing guidelines Must be present during interviewer training Need excellent understanding of questionnaire and goals of survey

15. Data Processing Supervisor Resolves data entry problems Maintains programs Oversees entire data processing system Must be present during interviewer training Must have excellent grasp of questionnaire Must have programming skills in SPSS and CSPro

16. Questionnaire Administrator Training Review list of checks in data processing chapter Give QA several clusters and check work Establish questionnaire storage procedures

17. Data Entry Training Begin when you have one cluster for each data entry operator Allows you to –Train data entry operators –Debug programs Practice verification at the same time When you have finished –Fix entry programs –Delete data files

18. Secondary Editor Training Wait until you have 3-4 clusters double-entered Give secondary editors –Copy of editing guidelines –A cluster’s error listing –The cluster’s questionnaires Review work with secondary editor Try to schedule a day when data entry operators aren’t working

19. Data Processing Equipment Data entry machines –Windows XP, 2000, Vista,7 or 8 –Supervisor’s machine –Windows XP, 2000, Vista,7 or 8 –Available disk drive space for all software and MICS data files Uninterrupted power supplies (UPS) Network Surge Protectors

20. Data Processing Equipment A printer Paper Toner cartridges/printer ribbons Flash drives (if network is not established) Green pens

21. Data Processing Rooms Data Entry –Desk space for the monitor, keyboard, and stack of keyed and unkeyed questionnaires –Area to store “in-progress” clusters Editing –Quiet space for editors to work Questionnaires –Must contain means (e.g., shelving) to organize questionnaires by cluster

22. Server and Keyer’s Directory Structure MICS5 CSPRO DATA contains data from main entry ENTRY contains data entry programs VERI contains data from verification entry

23. Supervisor’s Directory Structure MICS5 CSPRO BACKUP backup of verified data DICTS dictionaries used in all programs (not just entry) ENTRY contains data entry programs EXPORT programs to transfer data from CSPro to SPSS FINAL a copy of all edited data GPS GPS data entry program (if applicable) RAW contains all unedited data (just after differences resolved) SUPER all programs not related to data entry phase SPSS contains all SPSS programs used for export and tabulation WEIGHTS contains weights spreadsheet and data files

24. Data Entry Cluster reaches the office Cluster acceptance is done. All the questionnaires are counted and recorded according to their type and result code to the cluster tracking form (CTF). Cluster is sent to Supervisor MAIN DATA ENTRY First keyer enters the whole of the questionnaires of the cluster. Supervisor runs the structure check control. If all questionnaires are entered, gives to second keyer for verification and records this information to system and CTF. VERIFICATION Second keyer enters the whole of the questionnaires of the cluster. Supervisor verifies the main and verification data by the supervisor menu. If there is typing errors, lets the keyers correct them at their computers. If no problem, the raw data is backed up. Sytem automatically gives date, it should be written to CTF Supervisor records the information on CTF to the system. Cluster is ready for main data entry. Supervisor gives it to first keyer and records keyers information to system and to CTF.

25. After backing up raw data “Back up the final data” After backing up of raw data: Secondary editing is done by the supervisor menu. ERRORS NO ERROR Secondary Editor: By using the “Editing Manual “ the necessary changes at the data with “Modify the data” option at Supervisor menu is done. Supervisor follows the same procedures for every cluster If all procedures are completed for all clusters: Export the data to SPSS

42. Data archiving: rationale Collecting data is expensive. Data should be used beyond producing basic report. Survey microdata are valuable resources for government departments and academic researchers. Survey data constitute valuable and irreplaceable assets which should be managed in a way that encourages their widest possible use and re-use. At the same time, data collectors main focus should be protecting respondents while making microdata assessable.
