t. e. Body mass index ( BMI) is a value derived from the mass ( weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m 2, resulting from mass in kilograms (kg) and height in metres (m). The BMI may be determined first by measuring its components by means of ...
Statistics is a mathematical body of science that pertains to the collection, analysis, interpretation or explanation, and presentation of data, [8] or as a branch of mathematics. [9] Some consider statistics to be a distinct mathematical science rather than a branch of mathematics. While many scientific investigations make use of data ...
Anthropometric measurements also have uses in epidemiology and medical anthropology, for example in helping to determine the relationship between various body measurements (height, weight, percentage body fat, etc.) and medical outcomes. Anthropometric measurements are frequently used to diagnose malnutrition in resource-poor clinical settings.
In the operational definition, the weight of an object is the force measured by the operation of weighing it, which is the force it exerts on its support. Since W is the downward force on the body by the centre of earth and there is no acceleration in the body, there exists an opposite and equal force by the support on the body. Also it is ...
Measure (mathematics) Informally, a measure has the property of being monotone in the sense that if is a subset of the measure of is less than or equal to the measure of Furthermore, the measure of the empty set is required to be 0. A simple example is a volume (how big an object occupies a space) as a measure.
Dactylos - Ancient Greek finger breadth. Digit - length of a human finger. Digitus - Ancient Roman digit. Etzba - fingerbreadth. Fathom - the distance between the fingertips of a human's outstretched arms. Finger. Fistmele - the measure of a clenched hand with the thumb extended. Gradus - Ancient Roman step.
v. t. e. Geometry (from Ancient Greek γεωμετρία (geōmetría) 'land measurement'; from γῆ (gê) 'earth, land', and μέτρον (métron) 'a measure') [1] is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. [2] Geometry is, along with arithmetic, one of ...
Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. [1] The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg).
