Here’s a really quick idea for a matching activity, totally building off Pip Arnold’s excellent work on shape.

At the bottom of this post are six “Popular times” graphs generated today by Google when searching for the following places of interest:

1. Cafe
2. Shopping mall
3. Library
4. Swimming pool
5. Gym
6. Supermarket

Can you match which graphs go with which places? ðŸ™‚

## How long does it take a student to submit a swear word into a text analysis tool?

Update on the predictive text challenge

I haven’t heard anything from anyone with any problems, and there seems to be a bit of traffic to the challenge page, so hopefully this is going well. I’ll allow checking of the first list of reserved words tomorrow. Students should put in what they predict the readability score will be for each word. These predicted scores will be checked against the actual readability scores and students will be given an overall result e.g. 85%.Â Oh, and just because you’re a teacher too you’ll get this idea for an investigative question/problem……. How long does it take a student to submit a swear word into a text analysis tool?

Related “reading themed” statistical investigation ideas

Check outÂ http://josephrocca.com/randomsentence/Â where you can generate “random” sentences from books that are no longer under U.S.A. copyright restrictions – so books generally published before the early 20th century. You could compare the process for random sampling sentences from digital books to processes for random sampling sentences from physical books (so much here with different sampling methods). You could give students an actual physical book and challenge them to estimate the total word count (check using the digital version!), or get students to devise a way to compare the “readability” of two books, or….?

So what was so surprising?

Recap: I got 10 dominoes from a supermarket recently and was surprised to find that all 10 were different (there are 50 different dominoes to collect). Ok, so on the face of it this may look like a familiar (and not super awesome) starter. Collecting cereal cards, ice block sticks, seed packets…….. But I was surprised to see this because I was thinking that a random process like this would mean I should expect to see at least one double up e.g. like seeing runs of heads when you flip a coin. When I thought about it more, I realised I wasn’t taking into account there were 50 dominoes – this makes a difference.
