Why Engineers Ignore You & the Party is in Macau
Here are some of the latest and greatest Plotly plots! Check out our Tumblr to see this same post with the interactive plots embedded, and to find more awesome content.
How to Get an Engineer to Talk to You
Hired is a job marketplace. Engineers post their resumes and engineer-hungry-companies ask to interview them. This first chart comes from an analysis of what separates the successful bids from the unsuccessful ones. One of the factors examined is the ratio of the “offered” position’s salary to the “preferred” salary the candidate declares on their profile.
The histogram shows that almost half of “offered” salaries are lower than the candidate’s “preferred” rate (the median ratio is just above 1). However, the lineplot shows that the chance of an engineer accepting a company’s interview bid improves dramatically when the company’s bid is even slightly higher:
For an engineer with a $120,000 preferred salary, paying $10k more leads to a 20% higher chance of introduction, whereas paying $10k less leads to a 25% lower chance. To put it another way, very few people are willing to take pay cuts of even $10,000.
‘Fascinating’, ‘Inspiring’, ‘Ingenious’ — the Most And Least Viral TED Talks
Our own Chuck Bronson put together this bubble chart of data scraped from the TED archives. The y-axis shows the number of views each video attracted, and the points are sized by each video’s length. Color shows how the videos were categorized — tags range from “Jaw-Dropping” to “Informative”.
Viewership per-video is surprisingly even regardless of when the video was posted. The one exception is the set of talks posted in 2006, which may have achieved a kind of “golden oldie” status. Videos dating from 2007 onward average 1.1 million views per video, 2006-vintage videos average 2.6 million. I know I’ll never forget the evening my college boyfriend showed me Hans Rosling’s talk.
The Ages of Mathematical Geniuses, Over the Ages
The Fields Medal is often described as the “mathematician’s Nobel Prize.” But, while a Nobel Prize cannot be awarded posthumously, a Fields Medal isn’t awarded post-middle age. Anybody who has turned 40 before January 1st the year the medal is awarded is not eligible.
As Emilia Petrisor’s (empet) bar chart shows, we’ve had fewer and fewer wunderkinds in recent years. And more medalists have been brushing up against the upper age limit. Maybe it’s related to the greying of Nobel Prize medalists?
Is Macau the New Switzerland?
If you’re very rich and wondering where the party’s at, the answer might be “Macau”. Import.io made the plot, and has the story:
Macau’s growth started in 1999, when the territory was returned to China and turned into a gambling hub. In 2002, after Macau gave gaming licenses to six casino operators.
The six now run 35 casinos crammed into little more than 11.5 square miles. Gamblers flock into Macau mainly from mainland China, as it is the only territory where gambling is legal in the country.
Also — if you’re very rich and wondering where the party’s at— have you considered investing in a datavisualization startup?
“Do the Right Thing (Regarding World Affairs)”
We’ve got a new addition to our PewResearch profile, and it has to do with how much faith the world has in the American president. The stacked bar chart below is based off a 44-country “Global Attitudes” survey released July 14.
One thing to note about this plot is how subjective the question is — i.e. Israelis and Palestinians might agree on what they expect Obama to do, but disagree about whether that “thing” is “right.”
Dorothy is Probably Retired By Now, Anna is Ageless
Adding to our stack of FiveThirtyEight remakes, we’ve got this handy-dandy quartile chart showing age distributions by name. The median “Emily” is 17 years old, the median “Dorothy” is 74.
Girls’ names typically cycle in and out of fashion more quickly than boys’ names, which means that they have narrower interquartile ranges. For instance, almost half of living Lisas are now in their 40s, meaning that they were born at some point between 1964 and 1973.
On the subject of name fads, a while back a datavisualizer named “Dorothy” — who to my knowledge is pretty far outside the interquartile range for the name — put together a longscroll on names in popular music. The catch is that it ranges back to 1891, and ends in 2009:
