Nigeria - Multiple Indicator Cluster Survey (MICS4)-2011 Nigeria, Fourth round

Data editing began from the feild through the feild data editor and then the feild supervisor before getting to the state officers.
Then other stages through the processing include

(i) Desk officers at the zonal offices
(ii) Trained data editors from the headquarters sent to the zonal offices for data editing during the data entry
(iii) Data editing through the zonal offices editors before data entry
(iv) Competent data entry staff
(v) Verifiers

Data processing began from the Planning stage. Processing took place in the six geo-political zones of the Federation where the questionnaires were checked against cluster control sheet before the data entry.

If there were any missing questionnaire, there must be a quick contact with the team from the feild, for a re-interview of the respondent involved.

All completed quetionnaires were arranged cluster by cluster in numerical order of household number within the cluster (i.e from HH1 to HH10) and despatched
to the zonal offices

Each cluster was followed by the selection sheets

Double entries was done for the data entry using CSPro interface with embedded program to check the entries and prompt the operator in case of
inconsistencies in the age, relationship, caretaker/mother, education between the various questionnaires

The two data set was then copy and run a program that will compare the two and find the difference in them which was corrected until error free data
is gotten. Then secondary editing program was run on them to get correct clean data for exporting to SPSS
