it had caused the Australian government in the past. Pearson directly quotes comments made by John Howard during a radio interview‚ but uses these comments to emphasise his own key arguments rather than support those being made by Howard. By using quotes from other sources he broadens the scope of his argument and makes his own argument less of a personal crusade. Pearson also focuses on National Identity and determining “who we are”. Pearson acknowledges the current debate of National Identity by

The interconnected objects are represented by mathematical abstractions called vertices‚ and the links that connect some pairs of vertices

infinity. Karl Pearson (1895) first suggested measuring skewness by standardizing the difference between the mean and the mode‚ that is‚ . Population modes are not well estimated from sample modes‚ but one can estimate the difference between the mean and the mode as being three times the difference between the mean and the median (Stuart & Ord‚ 1994)‚ leading to the following estimate of skewness: . Many statisticians use this measure but with the ‘3’ eliminated‚ that is‚ . This statistic ranges from
