COVID-19: Essential Information

anonymous data: data that by virtue of the method of collection can never reasonably be connected with the person providing them. This can be accomplished by questionnaires that are returned by mail (in envelopes with no return address or other identifying markers), questionnaires that are collected by one of a group of subjects and returned to the researcher, or internet surveys (with software that renders it virtually impossible to connect answers with respondents). Questionnaires that collect data anonymously do not require a separate written consent; consent to use the data is implied in the respondent’s completion of the questionnaire (a statement to this effect should be affixed to the beginning of any such survey).
