range
Algebra
(noun)
The set of values (points) which a function can obtain.
(noun)
The set of values the function takes on as output.
Statistics
Examples of range in the following topics:
-
Range
- The range is a measure of the total spread of values in a quantitative dataset.
- In statistics, the range is a measure of the total spread of values in a quantitative dataset.
- The mid-range is the midpoint of the range; as such, it is a measure of central tendency.
- The mid-range also lacks robustness, as outliers change it significantly.
- Interpret the range as the overall dispersion of values in a dataset

Introduction
- But it is often easiest to write the range on a staff, as the two notes at the high and low ends of the range.
- This smaller range is called the tessitura of the part.
- Notice the similarity between this second definition and the term power range, sometimes used to describe the most powerful or useful part of an instrument's range.
- A register is a distinctive part of a vocal or instrumental range.
- For example, singers may speak of the head register, in the upper part of their range, and the chest register in the lower part of their range.

Visualizing Domain and Range
- Example 1: Determine the domain and range of each graph pictured below:
- The range for the graph $f(x)=-\frac{1}{12}x^3$, is $\mathbb{R}$.
- Example 2: Determine the domain and range of each graph pictured below:
- The range of the blue graph is all real numbers, $\mathbb{R}$.
- Use the graph of a function to determine its domain and range
-
Vocal Ranges
- The four main vocal ranges are:
- The ranges of the four voices overlap, but singers may find themselves straining or getting an unpleasant sound at the top or a weak sound at the bottom of their ranges.
- The names for some of these ranges are:
- Voices are as individual as faces; some altos will have a narrower or wider range, or the sweetest and most powerful part of their range in a different place than other altos.
- These are approximate, average ranges for each voice category.
-
Instrument Ranges
- Some other terms that are used to describe instrument ranges are:
- An instrument with a slightly higher fundamental will have a slightly higher range; an instrument with a much lower fundamental will have a much lower range.
- The ranges of some instruments are definite and absolute.
- But the ranges of many instruments are, like vocal ranges, not so definite.
- Other instruments may be a mix of absolute and indefinite ranges.
-
Range Wars
- Range wars were fought over water rights, grazing rights, or property and border disagreements.
- Range wars occurred throughout the American West throughout the late nineteenth century.
- Famous range wars included the Lincoln County War, the Pleasant Valley War, the Mason County War, and the Johnson County Range War.
- The Johnson County War, also known as the War on Powder River and the Wyoming Range War, was a range war that took place in Johnson, Natrona and Converse County, Wyoming in April 1892.

Measures of Variability
- The range is 8.
- What is the range?
- Therefore, the range is 4.
- Therefore the range is 6.
- The semi-interquartile range is defined simply as the interquartile range divided by 2.
-
Host Range
- A virus' host range is the range of cell types and host species a virus is able to infect.
- The host range of the virus will depend upon the presence of the receptors described above.

Trading off Equity and Efficiency
- Income taxes are a laddered progressive tax where income tax rates are set in income bands or ranges.
- Each tax rate corresponds to a particular income range; income above a tax range is subject to a higher tax rate that corresponds to a higher income range and income below a specific range is subject to a lower tax rate, similarly identified with a lower income range.
- Within any given income range, the tax rate is the same.
- The range can be identified as conforming to the concept of horizontal equity.
- However, income taxes are only proportional within specific income ranges.
-
Microwaves
- The prefix "micro-" in "microwave" is not meant to suggest a wavelength in the micrometer range.
- This frequency range corresponds to a wavelength range of 10 to 1 millimeter, so it is sometimes called the millimeter band.
- This frequency range is used for most radar transmitters, microwave ovens, wireless LANs, cell phones, satellite communication, microwave radio relay links, and numerous short range terrestrial data links.
- The range of frequencies and wavelengths is remarkable.
- Distinguish three ranges of the microwave portion of the electromagnetic spectrum
