Gresham College Lectures

Are Averages Typical?

Feb 19, 2013

Gresham College

Not necessarily, for example the average person has fewer than two legs! This is because some people have fewer than two legs but nobody has more than two, so dividing the total number of legs by the total number of people to get the average gives a number less than two. Average does not mean typical! The lecture will examine how the work in the 19th century of such mathematicians as Florence Nightingale, Adolphe Queteller and Karl Pearson on describing and quantifying variation and uncertainty laid the foundations for the theory of statistics as a mathematical discipline.Support the show
