Online surveys

Online surveys are surveys conducted over the internet:
 * can use web or e-mail
 * web is preferred over e-mail because interactive HTML forms can be used
 * response rates sometimes 90% before 2000, but have been dropping fast since then (now 2% - 30%)
 * often inexpensive to administer
 * very fast results
 * easy to modify
 * response rates can be improved by using Online panels - members of the panel have agreed to participate
 * if not password-protected, easy to manipulate by completing multiple times to skew results
 * data creation, manipulation and reporting can be automated
 * data sets created in real time
 * some are incentive based
