Large data set guidance
The AS and A-level Mathematics specifications require students to study a large data set during their course of study. More detail can be found in the DfE content document. The data set is chosen by each exam board, based on Ofqual guidance.
The large data set in exams
The AS and A-level Mathematics exams will include questions or tasks that relate to the prescribed large data set, giving a material advantage to students who have studied it.
For example, in the specimen assessment materials students who had studied the large data set would have gained a material advantage through:
- understanding the categories and sub-categories that the large data set uses
- understanding how values in the large data set are rounded
- knowledge of trends in the data
- knowledge of outliers and other anomalies in the data.
The data set is too large to be taken into an exam but suitable extracts may be used in an exam question.
