Data Processing
Data Editing
Data Processing: ISSA computer software was used for data entry preparation and data collected was keyed into 5 microcomputers. Computer operators for data entry were hired and trained for 4 days. The data processing team had the responsibility of checking the completeness of all received raw data, pre-entry data quality control and preparation for entry, data entry process, testing and running controlling software, producing data error report, re-entry data corrected, converting software provided by the UNICEF Resident Representative's Office in Ulaanbaatar and processing data according to the instructions. In order to ensure the quality of received data, a double entry method, comparing results was used for each questionnaire. The Team Leader and the computer programmer attended a Data Processing training course held in Bangkok in April 2000, during which the trainees received the necessary knowledge and skills to apply in the case of this particular survey. These skills included questionnaire computer design, data entry, quality control, correction and process, as well as the utilization of the commonly used software package, SPSS, for data integration and analysis for this survey. Some additional software work was carried out and applied to ensure consistency of the software to be used and country-specific questionnaires were designed for the Child and Development Survey-2000.
Data pre-entry preparation, quality control and data entry was carried out in July-August 2000 at a highly professional level and in a shorter time than expected. At this stage of the survey, the working group stayed in close contact with the survey regional office and some questions raised concerning software and mathematical methodology were solved very efficiently.
Survey data were processed using software based on the given designed questionnaire. The data processing was carried out in two stages. The goal of the first stage was to obtain a complete file of raw data according to the processing technology order and to ensure the quality of the data. This included following:
1.1 Data entry
1.2 Structure checks
1.3 Verification
1.4 Secondary editing
1.5 Production of verified and confirmed data set
The second stage aimed to produce cross tables enabling further analysis to be carried out. This included the following:
2.1 Entry of a variety of options and simulations
2.2 Production of output tables
After the completion of the data processing of the survey materials, statisticians analyzed particular indicators, checked consistency with other data sources, reviewed results, edited errors, and reviewed concepts and definitions of unclear indicators. Finally based on these, they developed a working document, which would be useful for the next survey, and wrote the survey report. The other data sources used for analysis and consistency checks were other official statistics compiled by the National Statistical Office, the Statistical Year Book (NSO), and the Mongolian government's Population and Housing Census - 2000.
Within the context of the Child and Development Survey-2000, another survey concerning "Children Surviving in Difficult Circumstances" was conducted, by attaching a further questionnaire (CDS-2) to the main survey, and collecting the data at the same time. This required each local government authority to provide information through questionnaire CDS-2, which was completed in August-September, 2000. Data from this second questionnaire was collected and processed, using similar pre-data preparation, quality control and software processing, and in addition sets of handbooks and instruction were designed for this specific survey and approved by the working group. Children surviving in difficult circumstances were desegregated by aimag and a database was established.
All related original raw inputs were delivered to the archive after the data process was completed. A working report on the survey organization will be submitted separately.
