CHAPTER 8. DATA ENTRY AND DATA PROCESSING
The data entry has already been mentioned during the data collection process. 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. The team leaders and the 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 needs 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. This can
either be done on the same ‘Master’ spread sheet, or on a ‘Second entry’ spread sheet which
can then imported into the ‘Master’.
c) Saving and Backing Up Your Work
Save the data entry sheets periodically as you work to prevent data loss in the event of power
failure.
Data Entry Procedures
For each facility all the data first needs to be entered into the ‘Master’ form. The second entry
can either then be done on the same ‘Master’ form, or else done separately on a ‘Second
Entry’ form and then imported into the first ‘Master form.
There are two ways of double entering the data. The first step in each method is to enter the
data for a particular facility the first time. The way you do this is as follows—
