Data
Entry & Verification
SESRC
typically follows a three step process: coding of questionnaires;
initial data entry input, and re-entry verification. In addition
there is a final validation step that occurs after all questionnaires
have been entered and verified.
The first step of this process is coding which consists of
trained SESRC staff reviewing each questionnaire to make sure
answers are eligible and conform to a set of specifications
set forth in the specific project coding manual.
The second
step of data entry consists of the initial entry of data in
the CATI system. The system prompts interviewers for valid
responses to every numeric question in the survey. When an
invalid response is entered, the computer alerts the interviewer
that the value is out of range and prompts the interviewer
for a valid response.
The third
data entry step is verification of initial entry. Verification
is when a different interviewer enters the same questionnaire
and its responses a second time into the CATI system. The
CATI system then compares the numeric entries and informs
the interviewer if a different response had been entered.
If there is a discrepancy between the two entries, the CATI
program then prompts the interviewer to make a correction
to either the initial entry, or to the verification entry.
The SESRC
performs verification on every questionnaire received, and
on every question within the questionnaire (100% verification).
