In statistics, stratified sampling is a method of sampling from a population which can be partitioned into subpopulations.
The General Certificate of Secondary Education (GCSE) is an academic qualification in a range of subjects taken in England, Wales and Northern Ireland, having been introduced in September 1986 and its first exams taken in 1988. State schools in Scotland use the Scottish Qualifications Certificate instead. However, private schools in Scotland often choose to follow the English GCSE system.
Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy, biostratigraphy, and chronostratigraphy.
Abitur, often shortened colloquially to Abi, is a qualification granted at the end of secondary education in Germany. It is conferred on students who pass their final exams at the end of ISCED 3, usually after twelve or thirteen years of schooling. In German, the term Abitur has roots in the archaic word Abiturium, which in turn was derived from the Latin abiturus.
Advanced Placement (AP) is a program in the United States and Canada created by the College Board. AP offers undergraduate university-level curricula and examinations to high school students. Colleges and universities in the US and elsewhere may grant placement and course credit to students who obtain qualifying scores on the examinations.
The law of superposition is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields pertaining to geological stratigraphy. In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will lie at the bottom of the sequence, while newer material stacks upon the surface to form new deposits over time. This is paramount to stratigraphic dating, which requires a set of assumptions, including that the law of superposition holds true and that an object cannot be older than the materials of which it is composed. To illustrate the practical applications of superposition in scientific inquiry, sedimentary rock that has not been deformed by more than 90° will exhibit the oldest layers on the bottom, thus enabling paleontologists and paleobotanists to identify the relative ages of any fossils found within the strata, with the remains of the most archaic lifeforms confined to the lowest. These findings can inform the community on the fossil record covering the relevant strata, to determine which species coexisted temporally and which species existed successively in perhaps an evolutionarily or phylogenetically relevant way.
In geology and related fields, a stratum is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either bedding surfaces or bedding planes. Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both bed and lamina. Related terms are substrate and substratum (pl.substrata), a stratum underlying another stratum.
The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian Highlands division. The physiographic province is divided into three sections: the Hudson Valley, the Central, and the Tennessee.
Biostratigraphy is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock strata by using the fossil assemblages contained within them. The primary objective of biostratigraphy is correlation, demonstrating that a particular horizon in one geological section represents the same period of time as another horizon at a different section. Fossils within these strata are useful because sediments of the same age can look completely different, due to local variations in the sedimentary environment. For example, one section might have been made up of clays and marls, while another has more chalky limestones. However, if the fossil species recorded are similar, the two sediments are likely to have been laid down around the same time. Ideally these fossils are used to help identify biozones, as they make up the basic biostratigraphy units, and define geological time periods based upon the fossil species found within each section.

In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved ("folded") during permanent deformation. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur as single isolated folds or in periodic sets. Synsedimentary folds are those formed during sedimentary deposition.
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region. It is the fundamental unit of lithostratigraphy, the study of strata or rock layers.
Joint Entrance Examination – Advanced (JEE-Advanced), is an academic examination held annually in India that tests the skills and knowledge of the applicants in physics, chemistry and mathematics. It is organised by one of the seven zonal IITs: IIT Roorkee, IIT Kharagpur, IIT Delhi, IIT Kanpur, IIT Bombay, IIT Madras, and IIT Guwahati, under the guidance of the Joint Admission Board (JAB) on a round-robin rotation pattern for the qualifying candidates of the JEE-Main. It used to be the sole prerequisite for admission to the Indian Institutes of Technology bachelor's programs before the introduction of UCEED, Online B.S. and Olympiad entries, but seats through these new media are very low.
Teresa Stratas is an operatic soprano and actress from Canada of Greek descent. She is especially well known for her award-winning recording of Alban Berg's Lulu. She has now formally retired.
Kirix Strata is a specialty desktop database tool designed for data processing and data analytics. Strata includes a range of features to perform data analysis and create reports based on structured data from local files and external relational databases.
The Central Board of Secondary Education (CBSE) is a national level board of education in India for public and private schools, controlled and managed by the Government of India. Established in 1929 by a resolution of the government, the Board was an experiment towards inter-state integration and cooperation in the sphere of secondary education. There are more than 27,000 schools in India and 240 schools in 28 foreign countries affiliated to the CBSE. All schools affiliated to CBSE follow the NCERT curriculum especially from class 9 to 12. The current Chairperson of CBSE is Rahul Singh, IAS.
In statistics, the Cochran–Mantel–Haenszel test (CMH) is a test used in the analysis of stratified or matched categorical data. It allows an investigator to test the association between a binary predictor or treatment and a binary outcome such as case or control status while taking into account the stratification. Unlike the McNemar test, which can only handle pairs, the CMH test handles arbitrary strata sizes. It is named after William G. Cochran, Nathan Mantel and William Haenszel. Extensions of this test to a categorical response and/or to several groups are commonly called Cochran–Mantel–Haenszel statistics. It is often used in observational studies in which random assignment of subjects to different treatments cannot be controlled but confounding covariates can be measured.
The Computing Technology Industry Association, more commonly known as CompTIA, is an American non-profit trade association that issues professional certifications for the information technology (IT) industry. It is considered one of the IT industry's top trade associations.
A Doctor of Law is a doctorate in legal studies.
Baker Cave is a prehistoric archaeological site, located on a small canyon near Devils River in Southwest Texas. Dating from circa 7,000–7,800 BCE, Baker Cave is a part of a system of rock shelters in the Lower Pecos Canyons region and was 120 feet long by 56 feet deep. The ceiling varied from 18 feet (5.5 m) at the mouth to just a few inches in the back.
