N.B. – The negative variances, as they are very small in magnitude, could be considered as zero.
c- Candidate, s- Station, e- Examiner, e:s- Examiners within Stations, cs- Candidates into Stations, ce:s- Candidates into Candidates within Stations, and random error.
Bold figures indicate representatives of the largest source of variance amongst the effects.
