A Level Statistics Notes and Worksheets

The topics are organised according to Units S1 and S2 of Edexcel A Level, but the arrangement of topics for other boards is very similar.

The notes may be useful to a student without access to a teacher or a textbook. Or possibly to a teacher looking for a quick source of some teaching material on a particular topic. They contain references to exercises - these refer to the Heinemann (blue) Edexcel textbooks.

There are not many worksheets in this section as in general I used the exercises in the textbooks. Those listed may be of use to teachers looking for a quick source of some extra questions. They are probably not much use to students as they do not have answers, except where stated. (In some cases I may be able to supply answers if requested.)
