Independence is a fundamental notion in probability theory, as in statistics and the theory of stochastic processes.Two events are independent, statistically independent, or stochastically independent [1] if, informally speaking, the occurrence of one does not affect the probability of occurrence of the other or, equivalently, does not affect the odds.
In 2010, Texas Commissioner of Education Robert Scott announced the successor to the TAKS, STAAR. The STAAR had intensified rigorousness and end-of-course assessments, instead of a unified 9th, 10th, and 11th-grade Mathematics, ELA, Science, and Social Studies test. Therefore, one would take an Algebra I test in order to pass Algebra I, and so on.
The official logo of the TAKS test. Mainly based on the TAAS test's logo. The Texas Assessment of Knowledge and Skills (TAKS) was the fourth Texas state standardized test previously used in grade 3-8 and grade 9-11 to assess students' attainment of reading, writing, math, science, and social studies skills required under Texas education standards.

Let X 1, X 2, ..., X n be independent, identically distributed normal random variables with mean μ and variance σ 2.. Then with respect to the parameter μ, one can show that ^ =, the sample mean, is a complete and sufficient statistic – it is all the information one can derive to estimate μ, and no more – and
In abstract algebra, a subset of a field is algebraically independent over a subfield if the elements of do not satisfy any non-trivial polynomial equation with coefficients in . In particular, a one element set { α } {\displaystyle \{\alpha \}} is algebraically independent over K {\displaystyle K} if and only if α {\displaystyle \alpha } is ...
Al-Khwarizmi's algebra is regarded as the foundation and cornerstone of the sciences. In a sense, al-Khwarizmi is more entitled to be called "the father of algebra" than Diophantus because al-Khwarizmi is the first to teach algebra in an elementary form and for its own sake, Diophantus is primarily concerned with the theory of numbers.

The parallels axiom (P) is independent of the remaining geometry axioms (R): there are models (1) that satisfy R and P, but also models (2,3) that satisfy R, but not P. In mathematical logic, independence is the unprovability of some specific sentence from some specific set of other sentences. The sentences in this set are referred to as "axioms".
For example, the logical independence of the parallel postulate was established, relative to the other axioms of Euclidean geometry, during the nineteenth century. The independence results most of interest in contemporary mathematics are for the most part relative to the axioms of ZFC set theory , the de facto standard foundational system.
