Management Decisions, Inc. employs formal policies and
procedures that ensure high quality in the data collection,
tabulation, analytic, and report-writing phases of each project.
We review the different types of interviewing techniques and
types of questions, and ways of handling different situations
(including "probes," "clarifications" and "don't knows"). The
interviewer's manual and the training process also cover
instructions for using hard copy materials and automated
terminals; issues of rotational and positional bias; and the
importance of interviewer manners. Once employees begin
interviewing, they are carefully monitored using on-line
For each project, interviewers are briefed in training meetings
before the data collection begins. A practice session is held,
with each interviewer conducting several interviews before the
start of the study. This increases their comfort level and helps
to identify potential data collection issues.
Completed interviews for each project are reviewed by a
supervisor, again guaranteeing completeness and accuracy.
Phone numbers, provided by clients or purchased through sampling
firms, are dialed a maximum of four times to complete a contact
and to conduct an interview. All calls are recorded, including
answering machines, no answers, refusals, and reasons for
termination. The disposition of each and every call dialed is
available upon request.
For paper-and-pencil interviewing, 100% of all data coding,
inputting, cleaning and structuring is reviewed by "checkers"
who assess the accuracy of the data and look for anomalies. Our
on-site CATI System simplifies data collection and increases the
accuracy of both collection and processing. In formatting data
for diskette and hard copy, responses are tabulated, checked for
accuracy, and tested for significance (if requested) before
being sent to clients.
We have successfully used recruited samples (by telephone,
e-mail, mail), Internet panels and custom samples (provided by
client) to combine the best of both worlds - the sample control
of traditional methodologies, with the flexibility of offering
an online option.
We carefully review all reports produced for clients to ensure
that interpretations are consistent with the quality and
condition of the data. All
statistical data tested by Management Decisions, Inc. is
cross-checked for accuracy.
