Students had answered 7 questions anonymously without any labels. Answers were distributed to groups and stem and leaf plots were quickly made. As a class we discussed which plot was our height in inches and which couldn't be. Which plot shows the age of an adult in our home and which doesn&#Ruthhttps://www.blogger.com/profile/08713501900116257736noreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-317959509492382802015-11-19T21:40:36.430+00:002015-11-19T21:40:36.430+00:00Excellent!

But then I got a job at the Bank of England after uni and worked on a project involving sampling and testing banknotes - hence I had to use confidence intervals etc. You never know where these statistical tools will be used. <br /><br />I'm also interested Johttp://www.resourceaholic.comnoreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-82591346647399151792014-07-30T10:54:24.769+01:002014-07-30T10:54:24.769+01:00It's useful to know what the mathematics is us...It's useful to know what the mathematics is used for and whether it serves a purpose or not. I can't help but feel though that if we didn't teach about this, some students may miss out on the opportunity to apply it appropriately. After all, we don't know what jobs our students will have and what maths they'll need. There are aspects of maths that are taught where we can'tMr Jeffersonhttps://www.blogger.com/profile/01120877950955798388noreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-39877133962244080412014-07-26T10:34:37.726+01:002014-07-26T10:34:37.726+01:00Just a follow up to this post... @srcav wrote an e...Just a follow up to this post... @srcav wrote an excellent blog post which is definitely worth a read, to see the other side of the argument.<br />http://cavmaths.wordpress.com/2014/07/25/stem-and-leaf-is-there-a-point/.<br /><br />Views on Twitter are mixed.
