What does "Analysis not possible" mean?

If you see the message “Analysis not possible” following a test in the Lexplore Portal, this means that the student's results cannot be analysed for some reason. This may be due to the student sitting too close (closer than 48 cm/19 inches) or too far away (further than 80 cm/31.5 inches) from the screen and eye tracker, or that the quality of the recording wasn’t good enough (less than 70% quality).

You will need to delete the results and retest the student. Please click here for further information about deleting students results.
