Disadvantages
|
| Rich Data- Although less
personal than interviews, phone surveys allows for more rich content
than mail or computerized surveys. |
Reluctance to participate-
With the amount of telemarketing calls people receive, there is
an automatic resistance to participate in phone surveys. |
| Follow up- Interviewers
can use "follow-up" questions to probe deeper into their responses
or to clarify confusing answers. |
Limited participation time-
People are reluctant to participate in telephone survey longer than
10-15 minutes. |
| Randomized samples- Since
nearly everyone has a telephone, it is easy to randomly select telephone
numbers to call. |
Difficult to reach during business
hours- People are difficult to reach by telephone, especially
during business hours since most people work during the day. |
| Improved efficiency-
Recent technological advances have allowed adaptive surveys to improve
efficiency and quality of decisions. For more information, review
our technology description. |
Difficult to standardize-
Since everyone has slightly different views and interests, the data
you receive will be difficult to compare across respondents (unless
forced choice response options are used. |
| |
Difficult to analyze data-
Since the data you will receive is more qualitative (descriptive)
than quantitative (numerical), it will be harder to analyze and
produce results (unless forced choice options are used). |
| |
Limited to verbal questions- With
phone interviews, pictures, diagrams, or product demonstrations
cannot be used in the survey. |
