Marking Guide

We will use a marking guide to help mark your reports and to provide you with feedback. The previous marking scheme is reproduced below.You may, of course, use the scheme to guide you in the production of your report, but bear in mind the following things...

1) We may well have to modify the marking scheme in the light of any changes in the analysis of - and the conclusions that can be drawn from - the different data you will be using.

2) Simply addressing superficially the various points in the marking scheme will not gain you good marks; we are interested in answers that demonstrate understanding.

3) The list should not be seen as exhaustive; we are often pleasantly surprised to be able to award students marks for things not included on the list.
