How Florence Nightingale Changed Data Visualization Forever - Scientific American

The design process in action in Victorian England:

Recognizing that few people actually read statistical tables, Nightingale and her team designed graphics to attract attention and engage readers in ways that other media could not. Their diagram designs evolved over two batches of publications, giving them opportunities to react to the efforts of other parties also jockeying for influence. These competitors buried stuffy graphic analysis inside thick books. In contrast, Nightingale packaged her charts in attractive slim folios, integrating diagrams with witty prose. Her charts were accessible and punchy. Instead of building complex arguments that required heavy work from the audience, she focused her narrative lens on specific claims. It was more than data visualization—it was data storytelling.

A/A Testing: How I increased conversions 300% by doing absolutely nothing

An oldie but a goodie. If you think you’re getting statistically significant results from A/B testing, you should probably consider doing some A/A testing.

In an A/A test, you run a test using the exact same options for both “variants” in your test.

99 Good News Stories You Probably Didn’t Hear About in 2019

The goal in putting these stories together has never been to create a warm glow, or lull anyone into a false sense of complacency. The challenges facing the human family right now are big and scary and there’s no guarantee we will overcome them.

As millions of people have demonstrated in the past 12 months though, action is possible, better solutions are available and a better future can be built.

How readable—Findings

The results are in for Daniel van Berzon’s most recent experiment into accurately measuring code readability. You can read the results and read about the methodology behind them.

Why Data Is Never Raw - The New Atlantis

Raw data is both an oxymoron and a bad idea; to the contrary, data should be cooked with care.

Stats: Creating (Phil Gyford’s website)

I quite like Phil’s idea of having charts like this. It might be a fun project for Homebrew Website Club to do something like this for my site.

Some lovely data visualisation here.

Web Performance Optimization Stats

If you ever need to pull up some case studies to demonstrate the business benefits of performance, Tammy and Tim have you covered.

Our World In Data

If you’re in need of some long-term perspective right now—because, let’s face it, the short-term outlook is looking pretty damn bleak—then why not explore some of Max Roser’s data visualisations? Have a look at some of the global trends in inequality, disease, hunger, and conflict.

Results of the 2016 GOV.UK assistive technology survey | Accessibility

The Government Digital Service have published the results of their assistive technology survey, which makes a nice companion piece to Heydon’s survey. It’s worth noting that the most common assistive technology isn’t screen readers; it’s screen magnifiers. See also this Guardian article on the prevalence of partial blindness:

Of all those registered blind or partially sighted, 93% retain some useful vision – often enough to read a book or watch a film. But this can lead to misunderstanding and confusion

Better business by design

Some good-lookin’ stats from a responsive redesign:

Total page views, a metric we were prepared to see go down with the redesign, are up by 27%. Unique visitors per week are up 14% on average and visits per week are up on average 23%.

Impact of Responsive Designs

I heartily concur with Luke’s call for sharing of data:

If you’ve had success with a responsive design, my plea to you is to please share what you’ve learned.

I’m going to see if I can get some Clearleft clients to open up.

Some insane numbers on the return on investment that a bit of responsive optimisation can bring.

Carousel interaction stats by Eric Runyon

I’ve never been a fan of carousels on websites, to put it mildy. It seems I am not alone. And if you doubt the data, ask yourself this: when was the last time you, as a user, interacted with a carousel on any website?

When the Nerds Go Marching In - Alexis C. Madrigal - The Atlantic

The fascinating story of how a dream team of geeks helped Obama to victory. Personally, I think it’s all about the facial hair. I mean, how could they lose with Trammell’s beard to guide them?

Mobile first: the revolution is well under way - Generated Content by David Storey

David takes a look at worldwide trends in web browsing, pointing out where mobile traffic exceeds desktop …and we’re not necessarily talking about smartphones here either.

It would be possible to travel from the Niger Delta on the west coast of Africa, to the horn of Africa on the east coast, without passing through a country where people surf more on desktop than a mobile phone.

LukeW | Data Monday: Mobile Browser Use

Luke collates some useful mobile browsing statistics once again. Most of it is quite US-centric, but this closing point is a whopper:

36 countries more than doubled their Opera Mini user bases in one year.
