The power law theorem of data set size The number of data sets of size n is inversely proportional to n There are vastly more small data sets than very large ones So small data sets are likely to have a much larger impact on the world than big data sets David Hand: Some comments on big data December 2013

No-one actually wants data What people want are answers Which may be extracted from data So data are only half the answer The other half is statistics, data mining machine learning and other data analytic sciplines David Hand: Some comments on big data December 2013
