Data Processing
Data Editing
The questionnaire was programmed using the Census and Survey Processing System software (CSpro) and CAPI for data capturing. A team responsible for data quality protocols was established for real- time online data checks, comprising a data administrator, who ensured the connectivity of CAPI devices to the server and monitored the downloading and uploading of data to and from enumerators in the field, as well as data editors, who checked for errors in the data downloaded from the server and communicated any corrections or requested clarification from the enumerators.
Other Processing
After the data was downloaded from the webbased system, a process of data cleaning was performed to prepare the data for the statistical analysis. This process implied the creation of unique datasets including household and individual information to allow for an analysis of children's activities by variables describing the household's context. Data cleaning was performed by an expert using Stata statistical software. Moreover, the results in this report accounted for the complex sampling strategy by considering clustering, stratification and weighting. According to the sampling strategy, estimates and standard errors were adjusted using the survey weights.
