For n = 1 or 2, the midrange and the mean are equal (and coincide with the median), and are most efficient for all distributions. For n = 3, the modified mean is the median, and instead the mean is the most efficient measure of central tendency for values of γ 2 from 2.0 to 6.0 as well as from −0.8 to 2.0.
the arithmetic mean of data values after a certain number or proportion of the highest and lowest data values have been discarded. Interquartile mean a truncated mean based on data within the interquartile range. Midrange the arithmetic mean of the maximum and minimum values of a data set. Midhinge the arithmetic mean of the first and third ...
L-estimators are often much more robust than maximally efficient conventional methods – the median is maximally statistically resistant, having a 50% breakdown point, and the X% trimmed mid-range has an X% breakdown point, while the sample mean (which is maximally efficient) is minimally robust, breaking down for a single outlier.
A mid-range speaker is a loudspeaker driver that reproduces sound in the frequency range from 250 to 2000 Hz. [1] Mid-range drivers are usually cone types or, less commonly, dome types, or compression horn drivers. The radiating diaphragm of a cone mid-range unit is a truncated cone, with a voice coil attached at the neck, along with the spider ...
Midrange computers, or midrange systems, were a class of computer systems that fell in between mainframe computers and microcomputers. [1] [failed verification]This class of machine emerged in the 1960s, with models from Digital Equipment Corporation (PDP lines), Data General (), and Hewlett-Packard (HP 2100 and HP 3000) widely used in science and research as well as for business - and ...
What does 'mid' mean? Think: a lukewarm bowl of mac-and-cheese or a three-star hotel, says Kelly Elizabeth Wright, a postdoctoral research fellow in language sciences at Virginia Tech. For example:
The term "middle-range theory" does not refer to a specific theory, but is rather an approach to theory construction. Raymond Boudon defines middle-range theory as a commitment to two ideas. The first is positive, and describes what such theories should do: sociological theories, like all scientific theories, should aim to consolidate otherwise ...
