Hello and welcome to Wikipedia.
Some of your edits prompt these tips: (1) Begin with a complete sentence, not a dictionary-style definition; (2) Highlight the title word or title phrase at its first appearance, like this. (3) Don't use gratuitously capitalized letters in article titles or section headings; e.g., do not call an article "Mathematical Statistics" or "Operations Research", but mathematical statistics or operations research. (You put in a link to "Mathematical Statistics". That article did not exist, but mathematical statistics did. The former now exists as a redirect page, because I created it a few minutes ago.

Statistics lead
editI've proposed a new lead section for the Statistics article. See Talk:Statistics#My attempt at article lead section and my comment immediately above that one. Comments welcome. - dcljr 19:37, 2 Sep 2004 (UTC)
