Advantages of Self-Administered Surveys

Readex has chosen to focus on the self-administered survey technique (mail and online) because it offers several advantages over alternative methods:

Respondents answer at their convenience.
There is no need to set up interview appointments.
Surveys are delivered wherever the mail or email goes: city or country, home or office.
No interviewer is present to inject bias in the way questions are asked.
The low cost-per-completion makes it an economical method of surveying large samples.
