In the TED talks video "The Best Stats You've Ever Seen," Hans Rosling discusses the importance of being able to visualize statistics in order to fully understand what they mean. He uses specific examples such as GDP, fertility rates, family income, and life expectancy in graphical displays for the statistics to be better understood. Rosling also emphasizes that statistics shouldn't be generalized. For example, he notes the variability in GDP per capita ($) and child survival rates (%) among African countries. It is unreasonable to assume that all countries within a given area are similar, and sometimes, only statistical displays like the ones that Rosling shows can help people visualize those differences. At the end of the video, Hans Rosling shows the linear relationship between GDP per capita and number of internet users within a countries. Rosling uses several different displays to prove that the way statistics are presented is just as important as the statistics themselves.
