A traffic light analysis is an exercise which represents and organises a large amount of data so that presentation of the data becomes easy and coherent. The use of the colours of a traffic signal has given this kind of analysis its name. It is a common enough statistical tool which is used by a number of presenters, but the logic of it must be understood. The report must ensure that adequate keys are provided along with the document for the ease of understanding of the viewers and the report is accurate.
