There are many longstanding unsolved problems in mathematics for which a solution has still not yet been found. The notable unsolved problems in statistics are generally of a different flavor; according to John Tukey, [1] "difficulties in identifying problems have delayed statistics far more than difficulties in solving problems."

The General Aptitude Test Battery (GATB) is a work-related cognitive test developed by the U.S. Employment Service (USES), a division of the Department of Labor. It has been extensively used to study the relationship between cognitive abilities, primarily general intelligence , and job performance .
The theory of statistics provides a basis for the whole range of techniques, in both study design and data analysis, that are used within applications of statistics. [1] [2] The theory covers approaches to statistical-decision problems and to statistical inference, and the actions and deductions that satisfy the basic principles stated for these different approaches.
Aptitude is inborn potential to perform certain kinds of activities, whether physical or mental, and whether developed or undeveloped. Aptitude is often contrasted with skills and abilities, which are developed through learning. [1] The mass term ability refers to components of competence acquired through a combination of both aptitude and skills.
The Special Tertiary Admissions Test (STAT) is a group of four scholastic aptitude tests used for admission into undergraduate programs at Australian universities, for students without a recent Australian Tertiary Admission Rank (ATAR). [citation needed] Some universities require STAT testing for admission to particular programs or courses.
In statistics, the method of moments is a method of estimation of population parameters. The same principle is used to derive higher moments like skewness and kurtosis. It starts by expressing the population moments (i.e., the expected values of powers of the random variable under consideration) as functions of the parameters of interest. Those ...
Among the more controversial issues debated in London 1830-1 were the financial settlement between the newly independent Belgium and Holland, and the territorial issue, with the disposal of Luxemburg and Limburg being especially inflammatory elements.
