Because Internet penetration among consumer and business populations is
currently limited, ADFR has developed a hybrid survey technique which
utilizes the power of online data collection in combination with traditional
methods and enables probability sampling which can be projected to larger
universes.
We have had particular success with a multi-media technique which
incorporates these three methodologies:
|
 |
A mailed self-administered questionnaire |
|
Providing a URL address which enables online response |
|
Telephone reminder follow-ups |
|
This technique has the advantage of reaching samples without regard to
Internet penetration, using the Internet to reach those respondents
comfortable with online response and increasing response rates with a
multi-media approach and telephone follow-ups. True probability sampling
can still be achieved with the convenience of easy online access.
This hybrid technique provides response rates which typically match those
from phone surveys, is less intrusive to respondents, provides high quality
data, allows for use of complex concept descriptions and visuals and
typically costs less than phone surveys. It is particularly of value for
larger samples requiring segmentation.
