  2. Frequency (statistics) - Wikipedia

    en.wikipedia.org/wiki/Frequency_(statistics)

    A frequency distribution shows a summarized grouping of data divided into mutually exclusive classes and the number of occurrences in a class. It is a way of showing unorganized data notably to show results of an election, income of people for a certain region, sales of a product within a certain period, student loan amounts of graduates, etc.

  3. Ulam spiral - Wikipedia

    en.wikipedia.org/wiki/Ulam_spiral

    Ulam spiral of size 201×201. Black dots represent prime numbers. Diagonal, vertical, and horizontal lines with a high density of prime numbers are clearly visible. For comparison, a spiral with random odd numbers colored black (at the same density of primes in a 200x200 spiral). The Ulam spiral or prime spiral is a graphical depiction of the ...

  4. Probability distribution - Wikipedia

    en.wikipedia.org/wiki/Probability_distribution

    A probability distribution is a mathematical description of the probabilities of events, subsets of the sample space. The sample space, often represented in notation by Ω ,{\displaystyle \ \Omega \ ,}is the setof all possible outcomesof a random phenomenon being observed. The sample space may be any set: a set of real numbers, a set of ...

    Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". [ 2 ][ 3 ]

  6. Student's t-distribution - Wikipedia

    en.wikipedia.org/wiki/Student's_t-distribution

    Gosset's paper refers to the distribution as the "frequency distribution of standard deviations of samples drawn from a normal population". It became well known through the work of Ronald Fisher, who called the distribution "Student's distribution" and represented the test value with the letter t. [13] [14]

  7. Probability mass function - Wikipedia

    en.wikipedia.org/wiki/Probability_mass_function

    Probability mass function is the probability distribution of a discrete random variable, and provides the possible values and their associated probabilities. It is the function defined by. The probabilities associated with all (hypothetical) values must be non-negative and sum up to 1, Thinking of probability as mass helps to avoid mistakes ...

  8. Ogive (statistics) - Wikipedia

    en.wikipedia.org/wiki/Ogive_(statistics)

    In statistics, an ogive, also known as a cumulative frequency polygon, can refer to one of two things: any empirical cumulative distribution function. The points plotted as part of an ogive are the upper class limit and the corresponding cumulative absolute frequency [2] or cumulative relative frequency. The ogive for the normal distribution ...
