Game of data

Game of data

This post is second in a series of posts where I’m going to share some strategies for getting real data to use for statistical investigations that require sample to population inference. As I write them, you will be able to find them all on this page. What’s your favourite board game? I read an article […]

Just Google it

Just Google it

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: Cafe Shopping mall Library Swimming pool Gym Supermarket Can you match which graphs go […]

Finding real data for real data stories

Finding real data for real data stories

This post is first in a series of posts where I’m going to share some strategies for getting real data for real data stories, specifically to use for statistical investigations that require sample to population inference. As I write them, you will be able to find them all on this page. Key considerations for finding […]

The power of pixels: Modelling with images

The power of pixels: Modelling with images

This post provides the notes for the plenary I gave for the Auckland Mathematical Association (AMA) about using images as a source of data for teaching statistical investigations. You might be disappointed to find out that my talk (and this post) is not about the movie pixels, as my husband initially thought it was. It’s probably […]

Cat and whisker plots – sampling from the Quick, Draw! dataset

Cat and whisker plots – sampling from the Quick, Draw! dataset

Last night, I saw a tweet announcing that Google had made data available on over 50 million drawings from the game Quick, Draw! I had never played the game before, but it is pretty cool. The idea behind the game is whether a neural network can learn to recognize doodling – watch the video below for […]

Helping students to estimate mean and standard deviation

Helping students to estimate mean and standard deviation

Estimating the mean and standard deviation of a discrete random variable is something we expect NZ students to be able to do by the time they finish Year 13 (Grade 12). The idea is that students estimate these properties of a distribution using visual features of a display (e.g. a dot plot) and, ideally, these measures […]

It’s raining cats and dogs (hopefully)

It’s raining cats and dogs (hopefully)

In April 2017, I presented an ASA K-12 statistics education webinar: Statistical reasoning with data cards (webinar). Towards the end of the webinar, I encouraged teachers to get students to make their own data cards about their cats. A few days later, I then thought that this could be something to get NZ teachers and students involved […]

Which one doesn’t belong …. for stats?

Which one doesn’t belong …. for stats?

If you haven’t heard of the activity Which one doesn’t belong? (WODB), it involves showing students four “things” and asking them to describe/argue which one doesn’t belong. There are heaps of examples of Which one doesn’t belong? in action for math(s) on the web, Twitter, and even in a book. From what I’ve seen, for math(s) I think […]

Statistical reasoning with data cards (webinar)

Statistical reasoning with data cards (webinar)

UPDATE: The video of the webinar is now available here. I’m super excited to be presenting the next ASA K-12 Statistics Education Webinar. The webinar is based on one of my sessions from last year’s Meeting Within a Meeting (MWM) and will be all about using data cards featuring NZ data/contexts. I’ll also be using the digital data […]

A stats cat in a square?

A stats cat in a square?

On Twitter a couple of days ago, I saw a tweet suggesting that if you mark out a square on your floor, your cat will sit in it.   Nobody has had a more productive day than my mother pic.twitter.com/LK6KX9KM1x — Danielle Matheson (@prograpslady) April 10, 2017 Since I happen to have a floor, a […]
