Math Links for Week Ending Nov. 1st, 2013


Spectacular visualization from the NBA. You choose the team and the player and see where they are hot and where they are not. They have also done some more detailed analysis of how entire teams do against each other that is pretty cool.

I am always on the lookout for datasets for analysis. Did you know the wettest place in Canada is Henderson, BC? Or that the coldest place is Snag, Yukon? Here is data on weather extremes in Canada

Correlation is often confused with causation. This is a problem when people believe that just because two variables are correlated that one of the variable's change is the cause of the other's. Here is a tutorial video on proving causation.

A throwback to Felix Baumgartner's Redbull Stratos Jump from Explore Learning. A full three part lesson with links to specific Gizmos. Now the lesson basically focus on physics but I still contend that all of the metrics that were on the screen as he first rose in the capsule that could be used for a lesson on ratio, rate and speed. When it was happening I actually took some screen shots. You can download all 20 of them here.

I thought this was a neat way to collect data. Play Mastermind and then do the analysis. In this case its done in a 4th grade class but this could easily be adapted to be done in a Data Management class when dealing with single variable statistics.

The myth of "I'm Bad at Math". A lot of discussion about this article on the Interwebs. Lots of people on both sides. Although the article doesn't mention it explicitly. The theory tends to be that many have what is called a fixed mindset rather than a growth mindset. That is, with a fixed mindset you think that you are born with a certain ability and that won't change. Whereas a growth mindset is when you believe that you can always continue to learn. Recent brain info seems to suggest that the growth mindset is supported. Check the following articles out for yourself.

That being said here is a counter point. Thanks to @mathtans for pointing this one out.

Here is some research to support the idea of how foster the growth model of learning

And to finish this topic off, let's hear about being a math major. I saw this a last week and forgot to put it in. Thanks to Sylvie Gava-Zompanti for reminding me of it.

Math links for Week Ending Feb 1st, 2013

How do you show a graph when you are on the radio? You convert it to music and have an opera singer sing it of course. I have just been getting caught up on some of my older podcasts and heard this great piece by Planet Money. Rather than just describe the graph seen on the right, they converted it to music and had it sung. Perfect for showing that data can be represented in many ways.

Is the Body Mass Index (BMI) really that useful if it says people like Brad Pitt are considered overweight? In fact, Dwayne "The Rock" Johnson is actually obese according to the BMI. Here's another adjusted measure. This could be used for teaching order of operations in Gr 7 or Gr8. Just sayin

Want to develop the value of Pi using Archimedes Principle of Exhaustion? Who doesn't? You can do it here at the Nova site with a handy dandy interactive applet. While you are there check out their other applets for math and science as well as full episodes of Nova.

Numberphile just released a video post compiling the results from their quest to find YouTube's favourite number. Here is the blog post that gives the detailed results of the data as well as the summary video and original videos. Great for any Data Management class

In the Numberphile post below you may have noticed that there are some limit expressions. These were produced by an online LaTeX equation editor that lets you create equations and then paste HTML code into your web pages (or images into your documents). A useful thing if you have ever needed to put math in a webpage

A great video by Numberphile on the problems with dividing by zero and the idea of 00. A nice discussion of and (and others).
