Commentary by Stephen Downes

Today's new word is from Dan Rehak's presentation (see above): Paradata. To quote from Wikipedia: Paradata are data about the process by which the data were collected. For example, the paradata of a survey "include the times of day interviews were conducted, how long the interviews took, how many times..., and the mode of communication (such as phone, Web, email, or in person). Thus there are paradata about each observation in the survey. These attributes affect the costs and management of a survey, the findings of a survey, evaluations of interviewers, and inferences one might make about non-respondents." See also Wordnik.
