Talk:Applied statistics

Help welcomed

My personal experience of this subject does not extend beyond economic statistics and quality control, so I should welcome inputs that put me right on other aspects. Also, I have had no mathematical training beyond the basic necessities of a professional engineer, so a mathematical input for the same purpose would also be welcome. By way of explanation of my drafting I should explain that I have in mind a readership of graduates and undergraduates that are neither statisticians nor mathematicians but may want to use statistics in their work or leisure. In view of the magnitude of the subject, I am trying to touch briefly upon most aspects, but long enough only to convey its flavour and provide links to authoritative references. I think that my cautionary notes in the text are justified by the damage done by the misuse of statistics, especially by my mathematical fellow-economists and their dramatic misapplication of statistics to financial risk assessment.

My thanks for help with definitions - and I look forward to further initiatives from mathematicians in creating further definitions. I would point out, however, that a definition that contains undefined terms is unhelpful. The current defimition of "sample" is a case in point. In my opinion it cannot be allowed to stand.

I should like to add a note to the glossary title on the Related Articles subpage to the effect that for mathematically precise explanations of the concepts, the reader should refer to the Statistics theory article. This does not seem helpful in the present state of that article, but perhaps I should do so in anticipation of its further development? Nick Gardner 10:53, 30 June 2009 (UTC)

Using "Related Articles" as a glossary works quite well for some terms, but not for all. There are some terms which never will get a page under this title, e.g. (Mean which needs disambiguation, or others for which the explanation is too long, or only suitable in a certain context.
(And a definition probably should not contain a displayed formula?) Peter Schmitt 12:45, 1 July 2009 (UTC)

I don't understand the choice "Library and information science". Shouldn't it be Mathematics, Sociology, Health Sciences, Geography, ... Peter Schmitt 12:54, 1 July 2009 (UTC)

I didn't know where to put it. There seems to be no obvious place for decision theory, or information technology which I am inclined to think are near neighbours. I did not want, for reasons that I have explained, to give the impression that it should be treated as a branch of mathematics. It is true that it uses a lot of mathematical theorems, but so does engineering - perhaps I should put it there? I think I will add it there, but I am open to suggestions.
