Data capture
………. is that painful interval between
enumeration and evaluation of the data
Not so good news ……
Data capture ?
No panacea !
Good news …… there are techniques which can assist,
& choices – are relatively few.
a) Internal
a) Keying
b) Outsource
b) Scanning – of some sort
+ Keying
Choice 1.
a) Keying – still has a place
b) Scanning – of some sort + Keying
Considerations
• Timeframe for producing results
• Type of Questions / Enumerator or Self Completion
• Questionnaire Design / Implications for Enumerators
• Accuracy ?? – of completion / of data capture
• ANTICIPATED CONDITION OF QUESTIONNAIRES
• SKILLS AVAILABLE
Scanning.
When the Enumeration is over, what happens next?

OMR / Key Correction Advantages
Quickest, simplest data capture method for well completed forms
Enumerator only needs to mark
HB Pencil + Eraser
Appropriate level of technology for current IT resources
Cost competitive solution – known / one time
OMR
OMR
Without question, OMR is the fastest & easiest way to capture
data
IF
the Questionnaire is filled out correctly
===========================================
It is easier to train 30,000 enumerators to mark
than it is to train them to correctly write, &
accurately position characters
5
Data Accuracy – at scanning
OMR – the scanner will recognise this 99.99%
of the time
IT Resources – current / available skills
Database Programming & Management
VB.net / Csharp etc program development
Choice 2.
a) Internal
b) Outsource
• Is there a capable & willing partner available?
• Is this really a potential opportunity for CSO
data capture resource building? At what stage of
IT resource development are CSO?
A third way?
Outsource scanning / CSO Key Correction !!
