Statistics can be very helpful in providing interpretation of reality but also can be used to distort our understanding. Discuss some of the ways in which statistics can be used or misused in different Areas of Knowledge to assist and mislead us, and how we can determine whether to accept the statistical evidence that is present to us.

When you turn on the news, what do you hear? 1 in 10 people in South Africa have AIDS , Unemployment Reaches New High of 9.3 Percent , etc. Statistics is supposed to convey information in an objective and comprehendible way to the general population.

However, according to journalist Ed Finn, many groups were omitted in these government surveys, "the under-16 group, those on strike or locked out and those who weren't actively looking for work in the four weeks prior to the survey. But by far the largest groups omitted from the list of jobless in the U.S. are the working-age men who are out of work because they are in prison or on parole." After adding these groups of people, the unemployment rate comes to 11.4%, a major difference caused by concealing the sample in which the statistics was based on.

Language is another great factor that can be used to distort our understandings of the numbers...
