Achieving a good response rate is a combination of two main factors, interviewer skill and good fieldwork practice.

TELEPHONE
PROS
*Sample control: efficiency - telephone ownership (landline, cell or VOIP) is almost universal, there are no geographical restrictions.
Sample control: sample frames - RDD (Random Digit Dialing) including mobile phone numbers makes frame errors potentially close to zero.
Field force control - interviewers can be supervised and monitored in real time.
Speed - large number of interviewers employed on a project can complete reasonably large samples relatively quickly.
Sensitive information - interview is reasonably anonymous and perception is that nothing is being committed to over the phone.
Low incidence rate - large numbers of screening calls can be made with reasonable efficiently and at relatively low cost.

TELEPHONE
CON
Diversity of questions/flexibility - restricted by participant’s ability to remember the answer choices or do the task. Ranking exercises and ‘single choice from many’ are impossible.
Physical stimuli - cannot be used except in a multi-stage project (recruit – mail out – recall).
Quantity of data - participant can break off the survey relatively easily; telephone interviews require concentration and are tiring, therefore data quality will deteriorate with long interviews due to satisficing.
Response rate - is becoming a problem due to sugging and frugging by non-research organizations and increased screening of calls via caller ID.
Participant control - the interviewer dictates the pace and the timing (at least of the initial contact).

Telephone is well suited to B2B interviewing, since it is a natural medium for most business target audiences. Often, however, the biggest challenge in B2B is finding the correct person to interview within the organization. This is more easily done by telephone than by other methods.

Ethical Considerations
Abiding by any local ethical guidelines, interviewers need to be prepared and able to tell participants where their telephone number has been obtained, the nature and purpose of the research, and in some cases be able to point the participant to a third party who will be able to confirm the legitimacy of the research company.

Observation research , like
passive measurement, gets
away from the problem of
awed recall by counting actual behavior, occurring in its natural setting.

Observation is not constrained by sampling, survey design or analysis issues. The observer simply sets up and counts.

Observers may also unwittingly impart an ‘observer bias’ if they are asked to make judgments about those they observe.

B2B CONSIDERSATION OBSERVATIONAL
Businesses may also be less than enthusiastic about opening their procedures up to scrutiny from what may very well be a competitor.

Question Diversity and Flexibility: More complex question types can be undertaken when there is an
interviewer present to help explain the task or when the questionnaire is visible to the participant.
Questionnaires may become more complex if intricate routing and survey logic is required.

Physical Stimuli: The need for this can range from the most basic (a visual representation), to touch and possibly also to smell and taste.

Sample Control: Defined as the ability of the method to reach the participants specified by the sample
definition. It can be broken down further into three useful components:
Theoretical Coverage: Is it possible, in theory, to reach all potential participants?
Sample Frames: To what extend do the lists you have available to you reduce the actual coverage?
Efficiency: Can the above two factors be mitigated by greater efficiency—the ease with which
qualifying participants can be found?

Quantity of data: How much information can be gathered will depend on the interest level the participant has
in the subject, how engaging the task is, and the ease with which the interview can be abandoned once
started.

Response Rate The majority of non-response in interviewed methods is made up of refusal and ‘not-at-
home’. Refusal can be reduced by actions taken by an interviewer (persuasion and follow-up/re-
contact). Not-at-home is reduced by repeated contacts at different times and days. In non-
interviewed methods the reasons for non-refusal are merely conjecture, non-response is reduced
through use of reminders

Environment: The situation the participant is in, both in terms of physical and psychological comfort and how conducive it is for concentrating on the survey and tasks.

Field Force Control: How easy it is to monitor and check the work done by interviewers, either in the selection
of participants or in administering the survey itself.

Interviewer Bias: The extent to which the interviewer, however unwittingly, conveys his or her own opinion
and thus suggests an answer which the participant is biased to agree with.
