I have taught Statistics from GCSE level all the way up to Undergraduate level and have files of notes and questions that I have accumulated over the years and recently was asked to post my notes on Sampling as many students don鈥檛 get the finer points and most textbooks don鈥檛 cover them either.

So here they are - I don鈥檛 think that the telephone directory is relevant so much to todays methods but have left it in for completeness.

Hope that you find them useful.
