More people want to learn statistics

More people want to learn statistics
Published on FlowingData

Data is hot right now, so as you would expect, more people are signing up and applying to learn about it. Quentin Hardy for The New York Times reports.

At North Carolina State, an advanced analytics program lasting 10 months has, since its founding in 2006, placed over 90 percent of its students annually. The average graduate’s starting salary for an entry-level job is $73,000. Its current class of 40 students had 185 applicants, and next year’s applications are already twice that. In 2009, Harvard awarded four undergraduate degrees in statistics. Two graduates went into finance, one to political polling and one became a substitute teacher. There were nine graduates in 2010, 13 last year. They headed into Google, biosciences and Wall Street, as well as Stanford's literature department.

And in 2011, just about everywhere.

從電話調查涵蓋率的觀點推估2012總統選舉結果

這是一篇從電話調查涵蓋率的觀點來推估2012總統選舉三組候選人得票率的一篇文章(劉念夏)

原文於2012.01.03 以working paper的型式刊載於國家政策研究基金會的網站
http://www.npf.org.tw/post/2/10192

當時的推估結論是
馬英九: 預估得票約在46.9%~50.2% (實際51.6%)
蔡英文: 預估得票約在43.4%~46.1%(實際45.6%)
宋楚瑜: 預估得票約在4.4%~9.5% (實際2.8%)

有點低估了馬英九的得票率, 並高估了宋楚瑜的得票率

各位研究先進 或可參考
