"Any realistic model of a real-world phenomenon must take into account the possibility of randomness... [M[ore often than not, the quantities we are interested in... will exhibit an inherent variation that should be taken into account by the model."

Graphs, plots, and charts


Here are links to pages concerning various types of statistical graphics. As with most of the site, this page and the pages to which it links are very much under construction. Only that which is blue and underlined is an active link. Please report any broken active links, typos, and other errors to Brother Brown at brownd@byui.edu. Thanks!
