Other forms of Data Appraisal
As a basic check on the quality of the survey data, the percentage of cases missing information on selected questions is shown in Table 3. 8.3 percent of household members (1764 persons) have missing information on their level of education but 0.1 percent (12 persons) have missing data on the year of education.
Among female respondents, 0.1 percent did not report a complete birth date (i.e., month and year). 0f women, who gave birth in the 12 months prior to the survey, 0.1 per cent did not report the data of AIDS testing.
A small number of children under 5 years old and between 6 and 8 years old, gave incomplete answers for the question on children with diarrhea in the last two weeks.
The data on weight and height is missing in the case of approximately four percent of surveyed children under 5 years old, which may be the result of the child not being present, refusal, or other reasons. Date on weight and height is the most likely information to be missing, but, by international standards, the above percentage is relatively low in comparison to other surveys in which anthropometric measurements have been taken (Sommerfelt and Boerma, 1994).
