How Low Should You Go? Low Response Rates and the Validity of Inference in IS Questionnaire Research
2006
Journal of the AIS
Preserved Fulltext
To illustrate how nonresponse error may bias findings in IS research, we calculate its impact on confidence intervals. ...
We believe IS researchers can and should do a better of job of improving (assuring) the validity of their findings by minimizing nonresponse error. ...
This is especially true of e-mail and web-based questionnaires that can reach a large number of people with the touch of a key. ...
