Mail Surveys
Mail Survey Design
The SESRC uses the Tailored Design Method (TDM) developed by Don A. Dillman to conduct surveys by postal mail. TDM is a method for collecting survey data that maximized survey response and is accepted worldwide as the premier method for conducting mail surveys.The SESRC can work with existing paper surveys, or let us develop a lightweight and effective survey instrument for you. TDM encorporates a multi-stage contact strategy which gives the researcher the ability to reduce non-response error.
Mail Room Facilities
A complete mailroom facility including high-quality, high-speed color printers, postal metering machines, folding machines and automatic mail assembling machines are operated on-site by trained mail-room personnel.Data Entry and Verification
Once mail surveys are completed and returned, the SESRC can conduct data entry in order to create a survey response database. SESRC typically follows a three step process: coding of questionnaires; initial data entry input, and re-entry verification with empahsis on controlling for entry error and data cleaning. In addition there is a final validation step that occurs after all questionnaires have been entered and verified.The steps of the process include:
-
Training personnel
-
Utilizing a project specific code manual
-
Review and coding
-
Inital entry
-
Quality assutance verification
