Web-Based Surveys
| Cost
web-based surveys can be conducted cheaply. |
Bias
obvious bias due to internet access. This is becoming less of a
problem (with some provisos). Internet access still different
across socio-economic groups. |
| Time
probably the quickest method of collecting data. |
Sampling Frame
there is no easily available sampling frame of residents
email addresses. Commercial suppliers can provide high volumes
of names. |
| Resource
little staff resource needed; software to send bulk emails
required. |
Response Rate
10-20% is an acceptable rate using this method. Response bias
is likely to be high. |
| Geography
easy method for including rural areas / remote communities. |
Respondent
no guarantee about who has completed the survey. |
| Design
need to be simple, but routing can be more complex (controlled
by computer programme). Good opportunity to use supplementary
materials. |
Literacy
unlikely to include those with low levels of literacy. |
