A **geographic coordinate system** is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

**Tibga ** is a department or commune of Gourma Province in north-eastern Burkina Faso. Its capital lies at the town of Tibga.^{ [1] }

The provinces of Burkina Faso are divided into 351 departments, whose urbanized areas are grouped into the same commune (municipality) with the same name as the department. The 351 communes created in those departments have three kinds of status :

**Gourma** is one of the 45 provinces of Burkina Faso and is in Est Region. The capital of Gourma is Fada N'gourma. The population of Gourma was 304,169 in 2006.

**Burkina Faso** is a landlocked country in West Africa. It covers an area of around 274,200 square kilometres (105,900 sq mi) and is surrounded by six countries: Mali to the north; Niger to the east; Benin to the southeast; Togo and Ghana to the south; and Ivory Coast to the southwest. The July 2018 population estimate by the United Nations was 19,751,651. Burkina Faso is a francophone country, with French as the official language of government and business. Roughly 40% of the population speaks the Mossi language. Formerly called the Republic of Upper Volta (1958–1984), the country was renamed "Burkina Faso" on 4 August 1984 by then-President Thomas Sankara. Its citizens are known as *Burkinabé*. Its capital is Ouagadougou.

The **duodecimal** system is a positional notation numeral system using twelve as its base. The number twelve is instead written as "10" in duodecimal, whereas the digit string "12" means "1 dozen and 2 units". Similarly, in duodecimal "100" means "1 gross", "1000" means "1 great gross", and "0.1" means "1 twelfth".

The number **e** is a mathematical constant that is the base of the natural logarithm: the unique number whose natural logarithm is equal to one. It is approximately equal to **2.71828**, and is the limit of (1 + 1/*n*)^{n} as n approaches infinity, an expression that arises in the study of compound interest. It can also be calculated as the sum of the infinite series

In mathematics, the **factorial** of a positive integer n, denoted by *n*!, is the product of all positive integers less than or equal to n. For example,

**ISO 8601***Data elements and interchange formats – Information interchange – Representation of dates and times* is an international standard covering the exchange of date- and time-related data. It was issued by the International Organization for Standardization (ISO) and was first published in 1988. The purpose of this standard is to provide an unambiguous and well-defined method of representing dates and times, so as to avoid misinterpretation of numeric representations of dates and times, particularly when data are transferred between countries with different conventions for writing numeric dates and times.

In mathematics, a **Taylor series** is a representation of a function as an infinite sum of terms that are calculated from the values of the function's derivatives at a single point.

The **slash** is an oblique slanting line punctuation mark. Once used to mark periods and commas, the slash is now most often used to represent exclusive or inclusive or, division and fractions, and as a date separator. It is called a **solidus** in Unicode, is sometimes known as a **stroke** in British English, and it has several other historical or technical names, including **oblique** and **virgule**.

The **Euler–Mascheroni constant** is a mathematical constant recurring in analysis and number theory, usually denoted by the lowercase Greek letter gamma.

**Compound interest** is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest. Compound interest is standard in finance and economics.

In geology, the places known as **hotspots** or **hot spots** are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. Their position on the Earth's surface is independent of tectonic plate boundaries. There are two hypotheses that attempt to explain their origins. One suggests that hotspots are due to mantle plumes that rise as thermal diapirs from the core–mantle boundary. The other hypothesis is that lithospheric extension permits the passive rising of melt from shallow depths. This hypothesis considers the term "hotspot" to be a misnomer, asserting that the mantle source beneath them is, in fact, not anomalously hot at all. Well-known examples include the Hawaii, Iceland and Yellowstone hotspots.

The **European route E 22** is one of the longest European routes. It has a length of about 5,320 km (3,310 mi). Many of the E-roads have been extended into Asia since the year 2000; the E 22 was extended on 24 June 2002.

The **45×90 points** are the four points on earth which are halfway between the geographical poles, the equator, the Prime Meridian, and the 180th meridian.

**Baingoin County** is a county within Nagqu of the Tibet Autonomous Region.

**Bossongri** is a town in the Bilanga Department of Gnagna Province in eastern Burkina Faso. The town has a population of 2,040.

**Doundougou** is a village in the Bilanga Department of Gnagna Province in eastern Burkina Faso. The village has a population of 309.

**Boudangou** is a town in the Manni Department of Gnagna Province in eastern Burkina Faso. The town has a population of 4,653.

**Margou** is a village in the Manni Department of Gnagna Province in eastern Burkina Faso. The village has a population of 641.

In probability theory and statistics, the **Poisson distribution**, named after French mathematician Siméon Denis Poisson, is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant rate and independently of the time since the last event. The Poisson distribution can also be used for the number of events in other specified intervals such as distance, area or volume.

**Namoungou** is a village in the Piéla Department of Gnagna Province in eastern Burkina Faso. The village has a population of 497.

In statistics, the **Jonckheere trend test** is a test for an ordered alternative hypothesis within an independent samples (between-participants) design. It is similar to the Kruskal–Wallis test in that the null hypothesis is that several independent samples are from the same population. However, with the Kruskal–Wallis test there is no a priori ordering of the populations from which the samples are drawn. When there is an *a priori* ordering, the Jonckheere test has more statistical power than the Kruskal–Wallis test. The test was developed by A. R. Jonckheere, who was a psychologist and statistician at University College London.
