Are scented candles a casualty of the coronavirus crisis? Our NodeXL #ddj mapping from November 23 to 29 found researcher Kate Petrova’s data analysis revealing that scented candles have suffered a blow in online reviews and a decrease in ratings, possibly linked to the coronavirus’ ability to affect people’s sense of smell. Elsewhere, Germany’s Zeit Online created a COVID-19 infection risk calculator, the COVID Tracking Project explained how holidays and weekends disrupt the recording and publishing of virus data, and Reuters analyzed the shortcomings of the coronavirus contact tracing system in England. Meanwhile, the Sigma Awards, which celebrate the world’s best data journalism, have opened for entries.
COVID-19 Infection Risk Simulator
What is the risk of being infected with COVID-19 if you share a space with an infected person at home, in the classroom, or in a restaurant? Inspired by a piece in Spanish newspaper El País, Zeit Online designed an interactive risk calculator based on a model developed by the Max Planck Institute for Chemistry. Users can adjust the conditions, with variables for the amount of time spent in same room, room size, number of people, wearing of masks, ventilation, height, speaking time, and volume, to see the probability of being infected via aerosol transmission. The story is available in German and English.
Tracking Trump’s Last Minute Regulations
With the inauguration of US President-elect Joe Biden set for January 20, time is running out for the Trump administration. As Trump loyalists try to push through dozens of policy changes before the handover, ProPublica is tracking the most controversial of these “midnight regulations.” Among those already finalized: allowing federal death row inmates to be executed by means other than lethal injection (such as shooting squads and gas), ending Medicare drug rebates, and restricting immigrant work visas by raising minimum wage requirements for some visa holders.
Scented Candles and COVID-19
Scientific illustrator Terri Nelson wondered if online reviews of fragranced products would be affected by the coronavirus’ ability to rob people of their sense of smell. Her finding: There were many angry reviews complaining that the scented candles they had bought had no smell. Nelson jokingly tweeted her observations and associated the negative reviews with COVID-19, which led curious researcher Kate Petrova to investigate the hypothesis. Petrova scraped about 20,000 reviews of the most popular scented and unscented candles and found that the ratings for scented candles have indeed fallen during the pandemic. The Washington Post published a piece on her data analysis. And here’s another take on perfume reviews by PhD student Moritz Wagner.
Sigma Awards Open for Entries
The Sigma Awards celebrate the best in data journalism around the world. Established last year in the wake of the now-discontinued Data Journalism Awards, the second edition of the Sigma Awards is open for entries until February 1. There’s a $5,000 cash prize to be split among the winners.
Holiday Disruption and COVID-19 Data
Holidays and weekends can result in a backlog of testing and reporting of COVID-19 infections, which causes the numbers to decrease and then, a few days later, to “catch up.” To determine how holidays, such as Thanksgiving, could potentially affect COVID-19 data, Erin Kissane, co-founder of the The Atlantic’s COVID Tracking Project, wrote an explainer based on US data from previous weekends and holidays.
Flaws in a COVID-19 Tracing System
England entered another lockdown on November 5 due to rising COVID-19 infections. According to a Reuters story, “With more than 12,000 additional deaths by Nov. 19 in the second wave, Britain is recording nearly four times more deaths per capita than Germany, though not as many as Spain or France.” Reuters analyzed the efficacy of the nation’s test and contact tracing system and discovered shortcomings and indications that lessons from the first wave were not learned.
Considering Rules for Data Visualization
At the Graphic Hunters online conference last month, Datawrapper designer and blogger Lisa Charlotte Rost gave a talk about the rules of data visualization, why some of the rules seem to contradict each other, and when to break them to design better visualizations.
Trump’s Empty Schedule
Aside from pushing through last-minute rules (see above), what has outgoing US President Donald Trump been doing since he lost the November election? According to research by The New York Times, he has attacked the legitimacy of the election more than 400 times since Election Day and went golfing at least six times. His public calendar seems particularly empty, with official activities recorded on the president’s calendar for only eight days between November 4 and 23.
Tips for Talking about Data in Audio Stories
“I spend a lot of time stripping scripts of details that reporters have put in…” explained economist and journalist Tim Harford, author of How to Make the World Add Up. “We can’t give people all the numbers; we can’t tell all the stories — so what’s interesting here?” Harford shared tips on creating compelling data-driven stories for radio and podcasts.
The Latino Vote: Not a Monolith
The strong Latino vote for Donald Trump in parts of Florida and Texas surprised pollsters, going against an assumption that Latinos would turn out for his Democratic opponent, Joe Biden. Bloomberg examined the vote precinct-by-precinct in three key US counties to analyze the shift in the Latino vote and identify possible factors behind the trend.
