How to do the Mann-Whitney U Test

I thought it was about time my A2 students got back into some statistics since the ones they learnt at AS so this week I introduced them to the creation of Henry Mann and Donald Whitney. Sadly some of my students seem to have a phobia of maths and the very mention of statistics sends them into a panic and they start expressing regret at having even chosen geography for A-level in the first place.

I had a similar experience myself at university until one of my good friends on the course showed me that it's actually quite simple once you approach it with an open mind! Since statistics forms an important component of many courses, not just geography, you may as well just accept it and do you best to understand, and you'll see, as I did, that it really isn't that bad! It's actually quite satisfying when you realise you can do it.

So, here are the resources I used for my lesson where I have tried to break it down to make it easy to understand.After re-capping which statistics they need to know for the AQA A2 Geography course, we did an example of MWU altogether on the board, then everyone tried out a second example on their worksheet. Hope it helps!
