Vlog 2

The topics this time are social learning, peer review, the sign test, measures of central tendency and dispersion and ethics.

The video lists the things you may be asked to calculate in the AQA exam. Regarding standard deviation (SD) I recently had the following communication from AQA:

Technically students could be required to calculate SD in an exam but it would take up most of the exam time to do so which would mean there would be trouble assessing a decent range of material on the paper as a whole. 
 
If students were required to calculate the SD then either way would be fine although it’s an interesting observation that substitution into a formula is on the list of maths skills so it would be appropriate to test it even if calculation of a solution was not ultimately required.
