DASHBOARD

The 'DASHBOARD' tab provides an overview of information about the survey status and its progress:

• Summary brings together key information about the survey: information about the survey, list of redirections to the survey, survey status, timeline, response rate and response by pages.

• Paradata provides an overview of the respondents based on the device, browser, operating system and the use of JavaScript.

• Item nonresponse provides information on the number of valid responses in relation to the total number of units which have been asked a particular question.

• Usable respondents give an evaluation of the usability of each questionnaire and are a supplement to the usual analysis of the status of units. The questionnaires are divided into groups based on the estimated usability: usable, partially usable and unusable; the boundaries of these groups can also be customized.
