The initial event driven data that emoTouch records in the database is called ‚Raw data‘. Although the Raw data contains the timestamp of the events with the best possible time accuracy, this kind of data is not suitable for most types of data analysis. For all analysis that include calculations on the actual of several participants (e.g. the calculation of the mean value of a slider position for all participants at a specific timestamp) you have to use ‚Resampled Data’ with a fixed sampling rate. ‚Resampled Data’ contains e.g. the actual position of a slider for all participants at discrete time intervals, e.g. every 100 milliseconds.

Nachricht im Original (Resampling)
== Notwendigkeit von Resampling == 
Die anfänglichen, event-gesteuerten Daten, die emoTouch in der Datenbank aufzeichnet, werden "Rohdaten" ('Raw data') genannt. Obwohl die Rohdaten den Zeitstempel der Ereignisse mit der bestmöglichen zeitlichen Genauigkeit enthalten, ist diese Art von Daten für die meisten Arten der Datenanalyse nicht geeignet. Für alle Analysen, die Berechnungen auf der Basis von mehreren Teilnehmern beinhalten (z.B. die Berechnung des Mittelwerts einer Schiebereglerposition über alle Teilnehmer zu einem bestimmten Zeitstempel), müssen 'resampelte Daten' ('Resampled Data') mit einer festen Abtastrate verwendet werden. Resampelte Daten enthalten in diskreten Zeitintervallen, z.B. alle 100 Millisekunden, die aktuelle Position z.B. eines Schiebereglers für jeweils alle Teilnehmer.

The initial event driven data that emoTouch records in the database is called ‚Raw data‘. Although the Raw data contains the timestamp of the events with the best possible time accuracy, this kind of data is not suitable for most types of data analysis. For all analysis that include calculations on the actual of several participants (e.g. the calculation of the mean value of a slider position for all participants at a specific timestamp) you have to use ‚Resampled Data’ with a fixed sampling rate. ‚Resampled Data’ contains e.g. the actual position of a slider for all participants at discrete time intervals, e.g. every 100 milliseconds.
