My thanks to Ord Adams, who has pointed me in the direction of a rather wonderful website called betterexplained.com
There are, let’s face it, any number of websites out there claiming to offer help to pupils who are having difficulty with maths, and you’d have to say the success rate of these sites is somewhat limited. But to my mind this particular website is a real success, because it goes one better: it offers better explanations for teachers. I’ve had a quick rummage round the website and am already impressed at how the author manages to give fresh insights into such matters, as, for example, this beauty on why radians are so useful. (Yes, I know, you can differentiate with radians… and degrees are arbitrary… but there’s even more to it than that, I assure you.) I’m not saying you’ll agree with everything he says, but the site will make you think.
Tell your friends. Tell your pupils. It’s that good.

Just been browsing this site again, and came across a brilliant explanation of all the different averages you can calculate for data: http://betterexplained.com/articles/how-to-analyze-data-using-the-average/
- very informative, especially regarding the harmonic mean!
