Computer Assisted Telephone Interview [cati]
NBS in collaboration with the World Bank carried out the survey using mobile phones and captured data in tablet, which was later uploaded to the server after verification. Both teams worked together to design and program the instrument in Survey Solutions, and put in place two layers of quality control measures. The first layer incorporated measures into the programing to ensure data accuracy, and metadata was followed closely to flag questionable entries. In the second layer, a supervisor was engaged to monitor the data collection effort and also to verify responses before uploading them to the server.
The data collection effort took three enumerators and a supervisor, who went through a two-day training in survey protocols, data capturing and uploading, and the questionnaire itself. The instrument was tested in house before the data collection started. The entire data collection process including the training took two and half weeks.
