Abstract

Nonsampling errors and their relationship to cost have been very difficult to quantify, especially in real time. Recent advances in paradata offer an opportunity to address this problem. This talk summarizes some recent developments in computer-assisted recorded interviews (CARI), mobile technology, global positioning systems (GPS), and dashboard design that improve our ability to monitor quality of data collection activities on household surveys.

  • For CARI, we report the results of an experiment to investigate quality improvements in interviewer behavior during interviews, by providing feedback on performance in several ways.
  • For mobile devices, we will demonstrate an application deployed on smartphones that enables interviewers to record outcomes of contact attempts in near real time and to report on their time use by type of activity, and provide some results from a national study in the U.S.
  • With GPS, we can track interviewer movement throughout the work day, and link it with activity data. These data will be used to create routing maps for supervisor review with the data collector to improve efficiency. We also report on experience running GPS falsification-detection techniques alongside more traditional methods.
  • A performance dashboard gives supervisors an at-a-glance view of key performance indicators on production, cost, and quality; signals quality anomalies that need immediate attention; and supports drilling down and through paradata systems to investigate problems. The talk will address issues in quantifying nonsampling errors and costs, using visualization and process quality monitoring techniques.
