Welcome to WikiProject Statistics

Some Wikipedians have formed this collaboration resource and group, whose aim is:

To improve Wikipedia's coverage of statistics and the organization of information and articles on this topic.

This page and its subpages contain their suggestions and various resources; it is hoped that this project will help to focus the efforts of other Wikipedians interested in the topic. If you would like to help, please join the project, inquire on the talk page and see the to do lists below.

This WikiProject covers articles related to statistics, including the history of statistics and biographies of statisticians. Articles within its scope include those in:

• List of statistics topics
• Category:Statistics and its sub-categories
• Category:Statisticians and its sub-categories

An expandable tree view of subcategories of Category:Statistics is available at CategoryTree->Statistics.

As of 5 December 2024, there are 5,256 articles within the scope of WikiProject Statistics, of which 3 are featured and 22 are good articles. This makes up 0.08% of the articles on Wikipedia, 0.03% of all featured articles and lists, and 0.05% of all good articles. Including non-article pages, such as talk pages, redirects, categories, etc., there are 13,786 pages in the project.

A ranking of articles on statistical topics by recent page views is at Wikipedia:WikiProject_Statistics/Popular_pages.

The list of statistics topics is being extended to include existing articles not previously listed and any new or unlisted statistics-related articles should be added. The list contains over 2750 items, including some redirects (18 February 2013: was 2642 on 17 October 2011; 2233 on 29 July 2009; 1731 on 31 December 2008; and 945 on 22 May 2008). The list is not at present very sophisticated and this project could undertake general improvements given that lists are far more versatile than categories. Look at lists of mathematics topics for examples.

Some priority articles that the project hopes to make progress with are those in:

• Category:Statistics stubs (314 articles)
• Category:Statistics articles needing expert attention (27 articles)

Guidelines

Here are general guidelines for different types of articles in the project.

• Consider adding one of these navigational boxes to the end of the article:

• {{Statistics}} (example: Statistical hypothesis testing)
• {{Least squares and regression analysis}} (example: Nonlinear regression)
• {{Experimental design}} (example: Randomized block design)
• {{Medical research studies}} (example: Randomized controlled trial)
• {{Statistics journals}} (example: The American Statistician)
• {{ProbDistributions}} (example: Binomial distribution)
• {{Theory of probability distributions}} (example: Probability mass function)

• Tag the discussion page with

{{WPStatistics|importance= | class=}}

and (if there is substantial mathematics content)

{{maths rating|field=probability and statistics | importance= | class=}}

using appropriate values for the class and importance parameters as described here.

General statistics articles

• Use one or more sub-category of Category:Statistics
• Tag stubs with {{statistics-stub}}

Probability distributions

• Suggestions regarding the structure of articles about probability distributions are here
• Include either of these infoboxes (feel free to leave some parameters blank):

• {{Infobox probability distribution}} (e.g., Negative binomial distribution)
• {{Infobox probability distribution 2}} (e.g., Geometric distribution)

• Add an appropriate sub-category of Category:Probability distributions
• Tag stubs with {{probability-stub}}

Biographies of statisticians

• Include {{infobox scientist}} with all known information.
• Add Category:Statisticians or one of its sub-categories
• Make sure you follow the policy on Biographies of living persons
• Add {{WPBiography}} to the article's discussion page (include "|living=yes" to the template for living persons)
• Tag stubs with {{statistician-stub}}, {{UK-statistician-stub}} or {{US-statistician-stub}}

Open tasks

Article-related tasks

Here are some tasks awaiting attention: Article requests : See requested articles in statistics, and in econometrics Cleanup : Articles in WikiProject Statistics are regularly scanned automatically for cleanup templates. A list of statistics articles that need cleanup is here. You can help by reviewing the list and correcting any deficiencies. Expand : Outline of statistics Outline of regression analysis Multivariate regression model needs detailed formulae for multivariate case Directional statistics to include measures of dispersion for circular data Conjoint analysis improve statement problem to be solved (more maths?)

New articles

An automatically generated list of new articles is available here, based on these rules.

Article assessment

Statistics WikiProject

The assessment is done in a distributed fashion through parameters in the {{WikiProject Statistics}} project banner; this causes the articles to be placed in the appropriate sub-categories of Category:Statistics articles by quality and Category:Statistics articles by importance.

Currently 6,918 pages have been tagged with the {{WikiProject Statistics}} template. Of these, 4 (0%) have not been assessed for quality and 906 (13%) have not been assessed for importance.

A log of recent changes in assessment is available here.
