Interviewers receive feedback
Reviewing recorded calls
Reviewing call recordings
• Automatically select random calls – targeted at
mistakes and policy violations
• Supervisors listen to and evaluate calls
• Determine whether interviewer correctly
described the outcome of the call
• Check for policy violations
Real-time call monitoring
• Assistant supervisors listen to calls during a
shift
• Evaluate six skills: verbatim, probing,
clarifying, feedback, pace, and voice
• Meet with interviewer during same shift to
discuss their performance
Real-time call monitoring
Miscoding Penalty Box
• Receive penalty box for
one call with low rating
on call skills
• Can also receive penalty
boxes for frequently
choosing the wrong
description of a call’s
outcome

third penalty box
Productivity
Top performer
This interviewer needs help
Measuring employee productivity
• Compare completed interviews per hour to average
for survey
• Average across time spent on each survey
• Interviewer score calculated over large 45-day
window to smooth out bad days
• Survey average calculated over smaller 15-day
window for higher accuracy
Rewarding top performers
• Productivity incentive for keeping score above
100%
• Incentive proportional to hours worked and
how far above 100%
• Some top performers earn over $600 in
productivity incentives for a 2-month
incentive period
Penalty box
• Required to keep productivity score above
– 84% for general interviewers
– 91% for spanish-speaking interviewers
– 107% for refusal convertors
– 117% for spanish-speaking refusal convertors
• Hold most skilled to higher standard
• Meet with supervisor after second box
• Terminated or demoted after third box
How Much Does A Survey Cost?
Negotiating a survey
• Estimate productivity per interviewer hour
• We try to get $26 per interviewer hour
• A survey where we complete one interview per hour
costs $26/complete
• A survey where we complete one interview every
two hours costs $52/complete

Sampling

sampling schemes
RDD – random digit dialing
• Numbers are created using information
about existing area codes (GENESYS)
• Best for obtaining a representative sample
• Less productive than listed sample
SAMPLING SCHEMES
Targeted RDD sample
• Overlay U.S. census tracts with working
telephone banks
• Targets specific subgroups
• Regions
• Ethnic groups
• Levels of income
SAMPLING SCHEMES
• Predetermined lists
• Efficient
• Cost effective
• Quality depends on the frequency of
updates

Do Not Call Lists
• National Do Not Call Registry (www.donotcall.gov)
• Only calls that solicit the sales of goods or services
are covered
• Surveys and charities are exempt
• Respondents usually do not know that
Common sources of lists
• Telephone numbers and households listed in telephone
directory
– Can pull national sample
– Unlisted numbers vary a lot by geographic area and respondent
characteristics
• Drivers licenses from state Department of Motor Vehicles
– Must select samples by state, and states vary in laws regarding drivers
licenses
– Data may be old as people move without informing Department of
Motor Vehicles
– Nor every one drives and there are biases (old and young, people in
urban settings with public transportation and high insurance costs)
Common sources of lists (continued)
• Voter Registration
– Potentially more updated than driver’s license database
– Not everyone votes – potentially very biased unless survey concerns
potential voters
• Lists from behavioral surveys and credit card evaluation
– Usually expensive
– Can often select people with particular characteristics (e.g. smokers)
– Potentially biased based on source
• Member and User Lists such as patient records, HMO
membership, recipients of Temporary Assistance for Needy
Families (TANF)
– Source is often variable in maintaining records (e.g. HMOs do not have
common database practices for recording membership data)
Telephone sample options and costs
•
$300 minimum on all orders
•
Random Digit Dialing (RDD)
uncleaned – $.04/record
•
RDD with business purging from
yellow pages – $.05/record
•
RDD with business purge and
attended dialing using automated
detection – $.09/record
•
Claritas Modeled data
•
Experian Behavior Bank – $.35/record
Example:
Consumer Confidence Survey
What is Consumer Confidence?
• Telephone survey based measure calculated each month from
the responses of approximately 500 Florida households
• Designed to predict consumer spending which accounts for
70% of Gross Domestic Product (GDP)
• Barometer of public opinion about economy
How is consumer confidence measured?
Consumer Sentiment from the
University of Michigan
Consumer Confidence from the
Conference Board
• 500 Random Digit Dial telephone
interviews a month across the
U.S.
• Approximately 3,500 mail out
surveys each month across the
U.S.
• Preliminary release second Friday,
final release last Friday
• Released last Tuesday
The University of Florida Survey Research Center uses
the University of Michigan method for Florida, but
releases the results the last Tuesday of each month

Our Survey Design
• Approximately 5,000 Random Digit Dial phone numbers released
each month
• Phone numbers are released proportionate to households by
county

Tuesday of each month with at least 400 completed interviews
• By the end of the month we collect at least 500 interviews
• Faculty can add questions to our monthly survey
