Box and whisker

One drawback of Microsoft Excel is that it does not have a function that easily allows for a box-and-whisker diagram to be generated. By ‘fudging’ together a stacked bar chart with error bars, this image was generated using Excel alone. The benefit is that I can just ‘copy and paste’ new data and the diagrams will update automatically.

I am pleased with the outcome, and the idea is that I will use it as the basis of a ‘starter’ in a lesson, as well as lessons in the future. However, I question whether the effort involved in achieving this is worthwhile.

I guess only time will tell how many times it is used.

A new venture

I have been reading a few maths teaching blogs on the internet over the last few months, which encouraged me to start my own (http://ttsjl.posterous.com/ ).

As I embark on the next stage of my career, I thought I would follow suit and blog my own mathematical teaching thoughts, successes and maybe even my failures. It is a bit of an experiment, but I hope that it proves to be useful to either me or somebody else.

We’ll see how it goes, but I’ll begin as I did in a recent statistics lessons – by displaying an image following my recent run in the relay for the school sports day. It certainly provoked discussion.
