This is a whole lesson to teach the basics of what the standard deviation is and how to calculate it. It comes with a starter, keywords, a link to a video, some great examples, some key questions, lots of activities embedded, worksheets and plenary. 18 slides!
This is suitable for both S1 at A-Level or KS5, but also excellent for those studying Statistics GCSE of doing it in other subjects, such as Geography. This does NOT go into areas like the normal distribution and some other applications of finding the standard deviation, this is just the first lesson on basically learning what it is and how to find it.
I have also included a basic excel calculator thing I created to help me find answers quickly and this also could be something to do with the pupils as a lesson in itself. I have included two sets of worksheets (exam questions with answers).
