Wandering and meeting Sarah, Edouard and Ludovico

This week, I found a link to David Ranzolin’s The Data Analyst as Wanderer: Pre-Exploratory Data Analysis with R. In it David considers “answering questions about the data at two junctures: before you know anything about the data and when you know only very little about the data”.

He used metaphor of wandering to discuss data analysis. He observed “data analysts may wander but are not lost. This post is for data analysts ready to wander over their data (with R)”.

David’s questions are:

  1. What is this?
  2. What’s in this?
  3. What can I do with this?

These sprang to mind when I found Sarah Milstein’s How to Fail When You’re Used to Winning (A guide for managing morale while pushing for innovation). In her post, Sarah observed:

Innovation is a buzzword for our era. It evokes the promise of profiting tomorrow from today’s changes in technology. The word innovation implies a clean, crisp path. That’s a lie. In fact, innovation requires enormous amounts of failure — which then presents leadership challenges.

She adds:

But any team that must experiment constantly will fail a lot, and repeated failure almost always depresses people. (Original emphasis)

This part of her post struck me forcefully:

a certain amount of failure is inevitable. Accountability lies not just in individuals taking responsibility, but in teams having a consistent way to learn from those episodes. (Original emphasis)

Sarah concludes her post with this exhortation:

Your path to succeeding at failure and maintaining morale will not be linear. You’ll stumble along the way and find yourself wanting to pretend you didn’t just trip. But stick with it. Teams that can maintain good spirits during hard times tend to win, and nothing feeds morale like success.

Waldemar Januzczak was the guide in my next phase of wandering. Here in Australia they re-showed his 2009 documentary on Edouard Manet. In part of the documentary he discusses Manet’s Old Musician painting with Juliet Wilson-Bareau. Juliet pointed out Manet’s techniques in the picture and his ability to create texture in his composition.

One example was the shoes of the two young boys:

Juliet’s observation was that by rubbing the existing paint of the shoes rather than adding white, the picture takes on a different perspective.

Juliet’s knowledge of Manet made this granular insight particularly powerful and sent me off thinking about how each of use sees nuances in performance and the data of those performances. She returned me to David’s three questions for wanderers: What is this?; What’s in this?; What can I do with this?.

Fortunately, Ludovico Einaudi was there to help me with these contemplations. One commentator noted of him “For Einaudi, composition can happen in different ways. He improvises at the piano, invents melodies in his mind, but also hears them during his sleep”.

Daniel Keane (2017) said of Ludovico’s music “Throughout its course, one is never sure whether one is listening to something very old or very new.”

I think this sentiment resonates with our experiences of data wandering and why David Ranzolin’s prompts are so helpful.

#WBBL03 Final

#WBBL03 concluded on 4 February with the Sixers’ win in the final against the Scorchers by nine wickets.

I have been following the performances of the eight teams in WBBL03.

Prior to the final, my profiles of the two finalists were:


Sixers’ median partnership profile when winning up to the final:


Scorchers’ median partnership profile when winning up to the final:

My data suggested that the Sixers’ median innings’ total when winning was 146 and losing 121. For the Scorchers, median win 136 and loss 124.

In the final, the profiles were:

Sixers (two partnerships)


The Scorchers won the toss and chose to bat first.

My estimate before the final: if the game went badly for the Scorchers they might score 94. The worst case would be a partnership sequence of: 23, 10, 5, 10, 11, 20, 0, 2, 12, 1.

The Scorchers scored 99 runs with a partnership sequence of: 23, 3, 3, 12, 20, 5, 5, 19, 4, 5.

In reply, the Sixers had their second highest first wicket partnership (64) of their WBBL03 season.

Never-Never pedagogical aspirations

I watched #TheGhan on Sunday here in Australia on the SBS channel. Like many others (181,000 peak time viewers), I found the 17 hour journey enchanting.

Dan Whelan, the writer and producer, said of the film of the 2997 kilometer journey from Adelaide to Darwin:

We set out to achieve three things: first, the feeling of being immersed on the journey; second, to shoot the landscape from the train in a way that would work to blend with text and pictures on screen; and finally, to keep the journey exciting and make the train a character in the documentary.

All three worked for me. I had lots of time to think about how these three characteristics relate to personal learning journeys.

Up in the Northern Territory part of the journey, south of Katherine, one of Dan’s texts really caught my attention … as the Ghan passed 30 kilometers to the west of Elsey Station Mataranka.

It was a quote from Jeannie Gunn‘s We of the Never Never (1908). She wrote about her experiences of living at Elsey Station:

Called the Never-Never, the Maluka loved to say, because they who have lived in it and loved it, Never-Never voluntarily leave it.

I thought this might be a wonderful pedagogical aspiration on a slow learning journey. Dan’s three aims for the Ghan film do translate into a Never-Never pedagogy:

  • Immersed on the journey
  • A shared landscape to blend resources
  • Keeping the journey exciting

… and being patient with each other and engaged on this voyage of discovery.
