Regular readers know I post previews of images that I create for articles in other online publications. Here are two spreadsheets and two Venn diagrams for an upcoming series of articles in Decoded Science about Bayes’ Theorem.
The chart above compares the success rates of two fictional surgeons for scheduled versus emergency operations. Dr. alpha has a higher success rate in each situation; but Dr. beta‘s overall success rate is higher. That, my friends, is a Yule-Simpson Paradox, or Simpson Reversal.
My article explains the math of the Yule-Simpson Paradox, with some examples of how the situation may arise.
There’s a practical side, too, whether you’re a marketer planning an A/B experiment; a patient trying to decide between competing doctors or medical treatments; or a student weighing educational programs.

Why Write a Pair of Cold Weather Running Tips?
As I explain in my DeHaan Fitness post, most of the other articles recommend “the right cold weather running gear”. That may help someone who is beginning running in winter. At that stage in my journey to fitness, I simply wore what I had. That included a cotton T-shirt, sweat pants, sweatshirt, a really old overcoat, an old toque and worn-out gloves. Now that I’ve earned some technical fabric T-shirts, and bought proper running pants and jackets, I’m much less likely to perspire heavily and then freeze.
But everyone else suggests buying the right clothing for running in the cold. So I wrote different tips for running.
My article relates two running tips for cold weather that one might not find elsewhere. Probably they have been suggested by others; but they felt rather new to me when I thought of them.
Why Publicize my Article on Cold Weather Running Tips?
As a freelance writer, my task is to convey my client’s message in a “voice” that authentically represents that person or company.
For example, a service company may want to project how helpful they are, and the results they can achieve. Perhaps each section of an article should include a “call to action”, such as “contact us to learn more”. A professional tone may be needed; or perhaps one of reassurance and comfort.
By contrast, when I write for Decoded Science, my articles blend my insight into the topic with the tone and style of that web site. Many other science articles adopt a passive voice: “The experiment was performed successfully, but significant capital expenditures were accrued”. That’s not the Decoded Science style (thank goodness!), but one must adapt to a publication’s requirements.
I’ve deliberately chosen an informal first-person voice for my DeHaan Fitness articles. That site provides some of my own views and experiences.
By contrast, the Toronto events covered in this site are usually written before the event. For example, I do not recount “what I did for March Break”; instead, my article covers what you might plan to do, locally, with your own family.
Why am I publicizing the article I wrote about a pair of tips for cold weather running? In part, to inform prospective clients that I can write in different styles. Use my contact information in the right-hand column when you need some ghost-writing for your business!
However, this publicity is also a public service announcement to other runners (and cyclists, hikers and outdoors enthusiasts) who may have the same problem as the young man I met while running in the cold the other week.
Thanks for reading about why I wrote an article with two running tips for cold weather.
