The Persuasive Power Of Statistics

Numbers are powerful. This is one of the reasons why statistics can be such persuasive pieces of evidence. People often mistake statistics as facts. We too often accept them as the truth without ever questioning their appropriateness and validity. Many people cannot read stats properly and so misinterpret their meaning. Methods of data collection can be inaccurate and manipulated in favour of a particular viewpoint.

Who? October 2010 issue of Scientific American that shows the results of an online survey conducted to examine the trust people put into science and scientists. The survey: 21,000 people responded online Results: People trust scientists more than friends or family, and much more than elected officials and religious authorities. Do these numbers aptly represent the feelings of society? No! Survey from biased sample. Conducted on the Scientific American and Nature websites, the poll represents the feeling of people that went to those websites for a reason, which was in all probability a scientific reason. Data represents the feelings of a largely scientifically literate sample rather than a random sampling of society, in which case the numbers might be quite different.

Data can be used creatively and manipulated in such a way that favours your position. This can be achieved by presenting charts/graphs in numerous different ways. Data Manipulation

Absolute Stats vs Relative Stats

It doesn't seem fair to not factor in the wealth of a country when assessing its military budget. So, if you take military budgets as a proportion of each country's GDP, a very different picture emerges.

Who has the most soldiers? Using whole numbers creates a skewed picture. China obviously has a huge population. Their army is bound to be huge.

If you adjust the parameters to a relative view, the image shifts dramatically. China plummets to a staggering 164th in the world league table. Relative stats give an accurate overall account while absolute stats mislead us.

Crime & Political Agenda Chris Grayling manipulate statistics to suggest a rise of violent crime during Labour's reign of power Compared British cities to TV series The Wire set in Baltimore New system of recording crime figures introduced by Home Office in 2002 Figures rose due to Police asked to record every complaint Violent crime figures rose more than a third in one year “When The Wire comes to Britain’s streets, it is the poor who suffer most. It is the poor who are the ones who have borne the brunt of the surge in violence under this Government”

Crime & Political Agenda continued.... Labour Home Secretary Alan Johnson said: “they have continually misled the public about crime. Up and down the country Conservative candidates are using these dodgy statistics" "Since 1997 crime has gone down by 36 per cent and violent crime by 41 per cent.” Government using a different set of data to show fall of crime - British Crime Survey, Originally an academic exercise to complement police figures now regarded in the Home Office closer to true figures. Suggest no one knows what the true picture is which could be Labour’s intention to avoid crime for their policy
