Relative change and difference

In any quantitative science, the terms relative change and relative difference are used to compare two quantities while taking into account the "sizes" of the things being compared. The comparison is expressed as a ratio and is a unitless number. By multiplying these ratios by 100 they can be expressed as percentages so the terms percentage change, percent(age) difference, or relative percentage difference are also commonly used. The distinction between "change" and "difference" depends on whether or not one of the quantities being compared is considered a standard or reference or starting value. When this occurs, the term relative change (with respect to the reference value) is used and otherwise the term relative difference is preferred. Relative difference is often used as a quantitative indicator of quality assurance and quality control for repeated measurements where the outcomes are expected to be the same. A special case of percent change (relative change expressed as a percentage) called percent error occurs in measuring situations where the reference value is the accepted or actual value (perhaps theoretically determined) and the value being compared to it is experimentally determined (by measurement).

Complement (set theory)

In set theory, a complement of a set A refers to things not in (that is, things outside of) A. The relative complement of A with respect to a set B is the set of elements in B but not in A. When all sets under consideration are considered to be subsets of a given set U, the absolute complement of A is the set of all elements in U but not in A.

Relative complement

If A and B are sets, then the relative complement of A in B, also termed the set-theoretic difference of B and A, is the set of elements in B, but not in A.

The relative complement of A in B is denoted B ∖ A according to the ISO 31-11 standard (sometimes written B – A, but this notation is ambiguous, as in some contexts it can be interpreted as the set of all b – a, where b is taken from B and a from A).

Formally

Examples:

If is the set of real numbers and is the set of rational numbers, then is the set of irrational numbers.

The following lists some notable properties of relative complements in relation to the set-theoretic operations of union and intersection.

Thrive (Casting Crowns album)

Thrive (stylized as THRIVE) is the sixth studio album by American contemporary Christian music band Casting Crowns. Released on January 28, 2014 through Beach Street and Reunion Records, the album was produced by Mark A. Miller. Musically, the album, whose concept was inspired by Psalms 1 from the Bible, has a rock and contemporary Christian sound with influences from folk and bluegrass. The album received mostly positive reviews from music critics for its lyrics and musical diversity, but some critics felt that some songs were too similar to the work of other artists or to their own previous work.

Thrive sold 43,000 copies in the United States in its first week of release; although this was short of projections to sell 75,000 copies, it peaked at No. 6 on the Billboard 200 and No. 1 on the Billboard Christian Albums chart, while also charting in Australia, Canada, the Netherlands, and the UK. The album was preceded by the lead single "All You've Ever Wanted", which peaked at No. 3 on the Billboard Christian Songs chart.

Thrive (charity)

Thrive (formerly called Horticultural Therapy) is a small national charity, founded in 1978 by Chris Underhill, that uses gardening to change the lives of disabled people.
