Not so good news ……

No panacea !

a) Internal

b) Outsource

a) Keying

b) Scanning – of some sort + Keying

Good news …… there are techniques which can assist,

& choices – are relatively few.

Considerations Considerations

• Timeframe for producing resultsTimeframe for producing results

• Type of Questions / Enumerator or Self Completion Type of Questions / Enumerator or Self Completion

• Questionnaire Design / Implications for EnumeratorsQuestionnaire Design / Implications for Enumerators

OMR / Key Correction AdvantagesOMR / Key Correction Advantages

OMR

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

OMROMRWithout question, OMR is the fastest & easiest way to

capture data

IFthe 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 scanningData Accuracy – at scanning
