CHAPTER 8 --- Data entry and data processing
The data entry has already been mentioned during the data collection process in Chapter 5.
The data entry sheets look identical to the written sheets, so it is just a process of transferring
the written material to the data entry worksheets. As far as possible, this should be done
during data collection, but it must be done carefully and be well checked.
Data entry general points
a) Ensuring accuracy
The quality of the information generated by the adherence survey depends on the accuracy
of data entry. Team leaders and survey coordinator have overall responsibility for the
quality of the data, and should supervise data entry personnel on a regular basis.
b) Double entry
All data need to be entered twice by two different people. This is because entering detailed
data such as long columns of yes and no can lead to a substantial numbers of errors. The
quickest and most efficient way to find these data entry errors is to have a second person
enter all data a second time and then identify where the items entered disagree.
c) Saving and backing up your work
It is recommended that you save the data entry sheets periodically as you work to prevent
data loss in the event of power failure.
Data entry procedures
To enter the data a new instance of the questionnaire should be opened. For instructions on
how to do this see section ‘Accessing Data Entry Forms’, Chapter 5.
