Small gatherings can be dangerous too

A small gathering of 10 people or fewer can seem like a low-risk activity, and at the individual level, it’s lower risk than going to a big birthday party. But when a lot of people everywhere are gathering, small or large, the collective risk goes up. For FiveThirtyEight, Maggie Koerth and Elena Mejía illustrate the reasoning. The collective part is where many seem to get tripped up. “Flattening the curve”...

Testing voting scenarios while we wait for the counts

As we wait for the votes to be counted in the remaining states, here are a couple of interactives to test the possibilities. The New York Times updated their graphic on all possible paths to the White House (the original from 2012). FiveThirtyEight also has their thing: Or, there’s this decision tree by Kerry Rodden: Or, you could carry on with your day as if nothing is happening and not...

Comparing correlation in the FiveThirtyEight and Economist election forecasts

FiveThirtyEight and The Economist take similar inputs but output different forecasts. Adam Pearce was curious about how the state-by-state correlations differed between the two models: Outside of the CA-DC-VT-WA and LA-MS-ND-KY clusters, where the 538 correlation dips below 0, the models are mostly aligned. Glancing over the outliers, it looks like the Economist might not have an equivalent to 538’s regional regression that groups states in the same geographic region...

Using the FiveThirtyEight model, see how the election odds shift with different scenarios

With each model update, FiveThirtyEight runs 40,000 simulations, or what-ifs, to calculate the odds for who will win the election. Their new interactive lets you experiment with all of the what-ifs to see how the odds shift when a candidate wins a state. It answers the question, “If ______ wins in ______ and in ______, etc., what are the chances of him winning the whole thing?” So if Trump wins...

Tips for not letting polls and forecasts occupy your mind for two weeks

For FiveThirtyEight, Nate Silver provides tips to stay less stressed staring into the darkness known at election forecasts: This is perhaps the single piece of advice we give most often at FiveThirtyEight, but it’s especially important in the final couple weeks of a campaign. After a lull this weekend, there are likely to be a lot of polls the rest of the way out. On any given day, it will...

NBA playoff win probabilities, animated over time

FiveThirtyEight publishes win probabilities for NBA games throughout the season. During the playoffs, they show chances of winning each round, and with each game, the probabilities shift. Adam Pearce animated these shifts, from the start of the playoffs up to now. Nice. The visualization. Not so much the Lakers. Tags: Adam Pearce, basketball, FiveThirtyEight

How to vote in each state

Each state is handling mail-in voting in a certain way with varying timelines and rules. FiveThirtyEight provides a straightforward state-by-state guide so you can see what your state is doing. I like the color-coded grid map doubling as quick navigation. You get the overview and a jump to the state of interest. Tags: election, FiveThirtyEight, voting

FiveThirtyEight launches 2020 election forecast

The election is coming. FiveThirtyEight just launched their forecast with a look at the numbers from several angles. Maps, histograms, beeswarms, and line charts, oh my. There is also a character named Fivey Fox, which is like Microsoft’s old Clippy providing hints and tips to interpret the results. One thing you’ll notice, and I think newsrooms have been working towards this, there’s a lot of uncertainty built into the views....

Where unemployment benefits are higher than lost wages

Economists at the University of Chicago analyzed unemployment benefits from the CARES act and compared them against median salaries for different occupations and by state. FiveThirtyEight highlighted the differences: The researchers uncovered other kinds of inequality, too. In some professions, like janitorial work, people who are employed by essential businesses are continuing to show up to their jobs under hazardous conditions. But in doing so, they may be eligible for...

Comparing Covid-19 models

FiveThirtyEight compared six Covid-19 models for a sense of where we might be headed. With different assumptions and varying math, the trajectories vary, but they at least provide clues so that policymakers can make educated decisions. If you’re interested in the data behind these models, check out the COVID-19 Forecast Hub maintained by the Reich Lab at the University of Massachusetts Amherst. They helped with the FiveThirtyEight comparisons and are...
