Aki Ito for Bloomberg: I really want to see the relationship of winning and teams who more deeply follow statistics.

Elegant way to present a pair of charts

The Bloomberg team has come up with a few goodies lately. I was captivated by the following graphic about the ebb and flow of U.S. presidential candidates across recent campaigns. Link to the full presentation here. The highlight is at the bottom of the page. This is an excerpt of the chart: From top to bottom are the sequential presidential races. The far right vertical axis is the finish line....

More candidates and earlier

For Bloomberg, Lauren Leatherby and Paul Murray describe the heightened eagerness to enter the race for United States president. The stacked timelines, looking like squished bunches of Twizzlers, shows when people entered and withdrew during past election seasons. We’re 536 days out and 23 Democrats are in. In contrast, there were 8 around this time in 2008. Tags: Bloomberg, election

Seeking simplicity in complex data: Bloomberg’s dataviz on UK gender pay gap

Bloomberg featured a thought-provoking dataviz that illustrates the pay gap by gender in the U.K. The dataset underlying this effort is complex, and the designers did a good job simplifying the data for ease of comprehension. U.K. companies are required to submit data on salaries and bonuses by gender, and by pay quartiles. The dataset is incomplete, since some companies are slow to report, and the analyst decided not to...

Tax changes for different groups

There’s less than a month until taxes are due. It’s the most wonderful time of year, isn’t it? As you probably know, there are some changes in deductions, limits, and refund amounts this year, but who the changes affect depends on many variables.

How America uses its land

Dave Merrill and Lauren Leatherby for Bloomberg visualized land use for the conterminous United States using a pixel-like grid map: The 48 contiguous states alone are a 1.9 billion-acre jigsaw puzzle of cities, farms, forests and pastures that Americans use to feed themselves, power their economy and extract value for business and pleasure. Using surveys, satellite images and categorizations from various government agencies, the U.S. Department of Agriculture divides the...

Using statistical models to win almost a $1B in horse-race gambling

Kit Chellel for Bloomberg tells the riveting gambling story of Bill Benter, who used statistics to model horse-racing in Japan. My favorite part is the pre-Internet process Benter took to collect data and predict results: Benter’s model required his undivided attention. It monitored only about 20 inputs—just a fraction of the infinite factors that influence a horse’s performance, from wind speed to what it ate for breakfast. In pursuit of...

Jobless Claims at Five-Decade Low

The number of Americans filing claims for unemployment benefits hasn’t been this low since Richard Nixon was president, according to new data from the U.S. Labor Department. The figures suggest a tight labor market in which employers are retaining employees because there aren’t as many available qualified workers, Bloomberg reported: Overall, the employment picture remains solid, with payrolls continuing to increase and the unemployment rate at the lowest since late...
