In statistics, an ogive, also known as a cumulative frequency polygon, can refer to one of two things: any hand-drawn graphic of a cumulative distribution function [ 1 ] any empirical cumulative distribution function.

A pentagon is a five-sided polygon. A regular pentagon has 5 equal edges and 5 equal angles. In geometry, a polygon is traditionally a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain.
In statistics, the frequency or absolute frequency of an event is the number of times the observation has occurred/been recorded in an experiment or study. [ 1 ] : 12–19 These frequencies are often depicted graphically or tabular form.
Period, the reciprocal of frequency; t represents: time in graphs, functions or equations [10] a term in a sequence or series (e.g. t n = t n−1 + 5) the imaginary part of the complex variable s = σ + it in analytic number theory; the sample statistic resulting from a Student's t-test; the half life of a quantity, denoted as t 1⁄2 [10] Top ...
GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
Frequency (symbol f), most often measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time. [1] It is also occasionally ...
The frequency of a geodesic polyhedron is defined by the sum of ν = b + c. A harmonic is a subfrequency and can be any whole divisor of ν. Class II always have a harmonic of 2, since ν = 2b. The triangulation number is T = b 2 + bc + c 2. This number times the number of original faces expresses how many triangles the new polyhedron will have.
