Informally, in frequentist statistics, a confidence interval (CI) is an interval which is expected to typically contain the parameter being estimated....

In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers...

In mathematics, a (real) interval is the set of all real numbers lying between two fixed endpoints with no "gaps". Each endpoint is either a real number...

for the same time interval, positive intervals are always timelike. If s 2 {\displaystyle s^{2}} is negative, the spacetime interval is said to be spacelike...

(sometimes called the diapason) is a series of eight notes occupying the interval between (and including) two notes, one having twice the frequency of vibration...

This analysis calculates features such as the PR interval, QT interval, corrected QT (QTc) interval, PR axis, QRS axis, rhythm and more. The results from...

confidence interval) and for practical reasons of measurement (measurement error). The mathematical effect can be described by the confidence interval or CI...

A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures...

methods exist:[citation needed] HR = 1000 · 60/(RR interval in milliseconds) HR = 60/(RR interval in seconds) HR = 300/number of "large" squares between...

measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material...

and an ideal of L. An interval in a poset P is a subset that can be defined with interval notation: For a ≤ b, the closed interval [a, b] is the set of...

characterized by particle energies of around 1019 GeV or 109 J, time intervals of around 5×10−44 s and lengths of around 10−35 m (approximately the energy-equivalent...

tritone is defined as a musical interval spanning three adjacent whole tones (six semitones). For instance, the interval from F up to the B above it (in...

classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio. This framework of distinguishing levels of measurement originated...

In Bayesian statistics, a credible interval is an interval used to characterize a probability distribution. It is defined such that an unobserved parameter...

inference, specifically predictive inference, a prediction interval is an estimate of an interval in which a future observation will fall, with a certain...

In music theory, a perfect fifth is the musical interval corresponding to a pair of pitches with a frequency ratio of 3:2, or very nearly so. In classical...

music and dance. With a score composed by Bill Whelan, it originated as an interval act during the Eurovision Song Contest 1994, featuring Irish dancing champions...

The QT interval is a measurement made on an electrocardiogram used to assess some of the electrical properties of the heart. It is calculated as the time...

of the heart after a heartbeat, giving rise to an abnormally lengthy QT interval. It results in an increased risk of an irregular heartbeat which can result...
