Data Management

Zerihun Associates has a large pool of field interviewers, supervisors, listing officers, regional coordinators and data processing staff experienced in small or large and complex surveys. For each project we run we retrain all staff in the household surveying techniques, the questionnaire’s concepts, quality control, anthropometric measurements, the tracking of households, and the use of electronic survey and survey hardwares. For a specific assignment, Zerihun Associates trains a higher number of people than it actually sends to the field to assure the continuation of the fieldwork in the event of interviewer attrition.
 

Zerihun Associates also maintains a policy of providing training to the whole survey team, including the data processing assistants, etc. This approach makes everyone feel more part of the whole and helps people to understand what role they play in the whole.

Typical survey training covers programs and contents including but not limited to:  

 

  • Survey techniques and concepts
  • Applications and functionality of electronic surveys
  • Quality control checks
  • Preparation of hard and soft copies of raw data files
  • Preparations of data files
  • General trouble shooting
  • Completing questionnaire
  • Translations
  • Mock interviews and pilot field interviews

Our data entry service includes database design, database testing and revising, data-entry training, double data entry, performance tracking and data cleaning. 
 
Data Protection

Zerihun Associates has robust data protection policies and procedures. Our policies include monitoring and limiting access to data, ensuring password protection and encryption on computers and certain file types, and locking storage facilities of hard copies. 

De-Identification of Data - All electronic data that contains personally identifiable information are always encrypted on computers, external hard drives, in emails and cloud storage facilities. Hard copy personally identifiable data are stored in separately and locked in highly-secured storage facilities from the other data to which its linked>>

   
The data protection policy applies to information or data that is personally identifiable such as name, ID number, address, telephone number, full face photos or any combination of information that could be used to identify the subject outside of the intended research context. In order to avoid inadvertent disclosure of such personal information, all Zerihun Associates staff follows procedures of De-Identification of data.
