EVALUATION OF THE USE OF PREVIOUSLY REPORTED DATA (PRD) IN
DATA COLLECTION
Purpose: To evaluate the impact of using
PRD on the response process during data collection and recommend guidelines
for its use to increase data quality.
For many ongoing survey programs, NASS will have data
from previous contactswith an agricutural operations available. To date,
NASS makes minimal use of this previoulsy reported data (PRD) during subsequent
contacts.
The objective of using PRD during data collection is to
increase accuracy of currently reported data. It also has the potential
to reduce the reporting burden for respondents. Previous studies have indicated
that PRD can increase data accuracy but also that it can prompt systematic
errors in reporting. PRD is currently being used for only a few selected
items in NASS survey interviews. With the increased use of computer assisted
data collection and accessibility of PRD, via the data warehouse, the number
of its potential uses is increasing. However, we do not always know how
PRD affects the reporting process, and more critically, how it affects
the quality of reported data and ultimately, survey estimates.
The goal of this project will be to provide the Agency
with more information and guidance on when to use PRD and recommendations
for how best to incorporate it into the interview process.
