, Glossary for mark schemes
GCSE examinations are marked in such a way as to award positive achievement
wherever possible. For GCSE Statistics papers, marks are awarded under various
categories.
If a student uses a method which is not explicitly covered by the marking instructions
the same principles of marking should be applied. Credit should be given to any valid
methods. Examiners should seek advice from their senior examiner if in any doubt.
Key to mark types
M Method marks are awarded for a correct method which
could lead to a correct answer.
A Accuracy marks are awarded when following on from a
correct method. It is not necessary to always see the
method. This can be implied.
B Marks awarded independent of method.
ft Follow through marks. Marks awarded for correct working
following a mistake in an earlier step.
SC Special case. Marks awarded for a common
misinterpretation which has some mathematical worth.
M dep A method mark dependent on a previous method mark
being awarded.
B dep A mark that can only be awarded if a previous
independent mark has been awarded.
