I swear I didn’t plan this! I was going to do socks or something like that, but anyway, here we are! The graphs and raw data are images to give the best accessability for everyone, but for those that want (email me) I can supply the spreadsheet in Open Office or Excel format.
For the geeky among us, the stats test I used was the
Spearmint Rhino Spearman Rank correlation coefficient. And just for Anne, I did the standard deviation (see the last photo).
I made the pics fairly small on the blog for those on dial-up or restricted bandwidth. Click on the pictures to be taken to Flickr where you will be able to see them full-sized (or larger in any case). If you use Firefox, simply right-click on the pictures and choose “Open in New Tab” from the menu; that way you will be able to keep this post open while you look at the pictures.
Note: the straight line is the linear regression for each graph.
What does all this mean? My mum and me aren’t all that unsual after all! There is a strong correlation between heel depth and ankle circumference, foot circumference and foot length. Plus, I made some pretty graphs!
Thanks for indulging me, and I hope that you feel you’re contribution was worthwhile.
S is also for Science. Here’s a quick round up:
