accuracy, schmaccuracy.

Standard

it’s ground hog day once again, and poor phil. the famous groundhog

will get pulled out of a deep winter’s sleep.

many will gather to see what phil will predict.

will spring be just around the corner, or delayed for another few weeks?

how accurate are his predications, really?

At Gobbler’s Knob in Punxsutawney, Pennsylvania, weather-predicting groundhog Phil may see his shadow, which means he’ll call for six more weeks of winter-like conditions. Don’t get too bummed, though—Phil’s recent track record isn’t that great on the national level.

The tradition started in 1887, and since then, the groundhog chosen to represent Phil has seen his shadow 101 times. 

Phil has predicted 100% correctly in only five of the 26 years the National Climatic Data Center analyzed. Other than once, he only nailed the years in which he forecasted an early spring. Considering the contiguous United States just experienced its 2oth+ consecutive year with an above-average annual temperature, Phil may be wise to play the numbers and always predict an early spring.

Then again, perhaps we expect too much from a marmot with no access to nationwide climate data.

“well, the way we perceive accuracy and what accuracy is statistically

are really two different things.”

puxatawny phil with some other (less famous) celebs.

it’s his big day, and one of my favorite fun holidays

no matter what he predicts

about the coming of spring

(*not sure about his accuracy)

 i love his spirit. 

 *the national climatic data center compared U.S. national temperatures from 1988 to 2012 to determine the accuracy of Phil’s predictions, and he’s only been proven correct 39% of the time — significantly worse than chance.

the big guy checks out the situation.

“Groundhog found fog. New snows and blue toes.

Fine and dandy for Valentine candy.

Snow spittin’;

if you’re not mitten-smitten,

you’ll be frostbitten!

By jing-y feels spring-y.”
