2009: Human rights & democracy statistics by Hans Rosling.  In this video, made for the Oslo freedom Forum 2009, Hans Rosling talks about the difficulty in measuring progress in Human Rights in the form of comparable numerical statistics. He also shows the surprisingly weak correlation between existing estimates for democracy and socio-economic progress.  The reason may be that democracy and human rights measurements are badly done. It may also be that democracy and human rights are dimensions of development that are in themselves difficult to assign numerical values. But it also seems as much improvement in health, economy and education can be achieved with modest degrees of human rights and democracy. Hans Roslings concluding remark is that Human rights and Democracy maybe should be mainly regarded as values in themselves rather than means to achieve something else.  (Uploaded by Gapcast on May 23, 2009) [9:52 long.  21,081 views 6/2012]

Peter Holmes Keynote at ICOTS-6 (July 7-12, 2002 Cape Town, S. Africa):  Video   Audio-only    Over many years I have been attempting to improve statistical literacy in the population by changing the school curriculum. All such attempts have to be put in the general context of teaching, learning and assessing the subject. Ideally these should complement and reinforce each other. In practice they often conflict, in particular assessment can distort the learning process. In this talk I shall consider the nature of these conflicts and how they might be overcome in practice, giving examples from a lifetime's practical experience.

Statistical Literacy: Where do Official Statistics come from [24:50] 

BBC - The Code - The Wisdom of the Crowd [4:50]  BBC's prof. Marcus du Sautoy explains how a group of people know more than one individual. Amazing stuff! The explanation is not hard to understand, but still it is hard to believe.  In his paper "Vox Populi" published in Nature, March 7, 1907, Sir Francis Galton investigated this wisdom at a Fat Stock and Poultry Exhibition.  Attendees were asked to guess the dressed weight of an ox.  The median of the crowd's guesses was 1207 lbs., so the crowd was off by only 9 pounds out of 1198 or less than 0.8%. This was better than any individual guess, even from the experts.   Much to his surprise he concluded that "This result is, I think, more creditable to the trust-worthiness of a democratic judgment than might have been expected."
