Standardisation: Principal Assessor, Senior Team Leaders and Team Leaders Marking: Marker briefing, practice and qualification Seeded papers and additional sampling Marker Reports Exceptional Circumstances Marking Review

10 Setting Grade Boundaries
Marker Reports The analysis grid for the paper Statistics: facility values; discrimination Grade boundary meeting: Senior SQA personnel Did the assessment perform as predicted?

11 Understanding Standards
Question Paper Workshop 1 Calculations

12 Units Common mistakes: KJ or kJ Kelvin Equilibrium constant - K mol-1 or mol l-1 Rate constant - k

13 Significant Figures

14 Significant Figures Fewest number of significant figures in data is 2.

15 Significant Figures Answer in calculator: Answer should be to 2 significant figures. -130 However, 1 fewer is acceptable: -100 and up to two more are also acceptable: -128 -127.5
