GCSE: no mention of "skew" in specifications.

    • Is there no requirement to use the term "skew" when describing or comparing distributions? The term doesn't show up when searching specifications for various exam boards - if it was removed, when did that happen?

    Never been in Edexcel GCSE. It disappeared from A Level in 2017 with the new syllabus, though students need to know that Normal is symmetric and Binomial isn't unless p is close to 1/2.

    As adam has stated, it isn't in the maths specification, never has been.

    It does feature in the statistics GCSE content, both identifying it by inspection for histograms & box plots, and by calculation using the given formula.

    Thanks for the replies - I think it must have been in the AO level I was teaching 2008-9 as I have a resource dating back to that time but all my teaching materials from that data are on an old laptop that I haven't got a working power adapter for - probably easier to take the drive out and shove it another machine to get at all my old lesson plans, objectoives, SoW, etc. I just wondered if it had been in recent GCSE specs but had been stripped out. Glad I asked.
