The Email survey (part 2)
(Information on the phone survey was presented orally during the
conference presentation. It is not detailed here.)
Response rates to the various surveys
Number of responses by date of receipt of response
Cummulative responses by date of response
Are surveys collected via Email comparable with those collected over the phone?
Number of respondents by type of survey and their use of WONDER
T-Test results comparing
Email and Phone
respondents on some key questions
These questions dealt with the extent to which respondent's felt
that WONDER was important to them. Question's were scored from
1 (not important) to 5 (very important) and a negative T-Test
value indicates that Email respondents had a higher rating for
the particular issue compared to Phone respondents. This table
presents results both for the total sample in each group as well
as broken down into levels of usage for WONDER.
Are the results comparable (continued)
Implications and future
research
At this time, I am undertaking a randomized-design experiment
with another center of the CDC. For this experiment, I will be
distributing a survey via Email, Phone, and Mail. The results
of this project will highlight the differences in responses and
response rates (based on the media) as well as cost differentials.
If you would like any further information on either of these two
projects, or some of the other projects I am working on, please
feel free to contact me.
Happy Surveying!!
