If it is that well established I am sure you will be able to give us loads of examples of political/social research companies and government departments illustrating their findings to one decimal place.
Obviously the detailed calculations are carried out to several decimal places during the analysis, but they are virtually always demonstrated publicly by charts using rounded whole numbers. For a lot of my working life I was responsible for some of the statistical outputs in the annual reports of a large company so for once I do know a little bit about the subject.
You still keep on throwing around this phrase "double standards" as if it means something. What exactly are the "double standards" wrt to this particular issue of rounding up statistics? Who is saying one thing and doing another?
i would if i could be remotely bothered.........What company was that Mothercare??? and when did you qualify is a data analyst??? or did you just produce data reports and think, hey i know more than everyone on the subject
