midrange

Midrange is a statistical measure that represents the center of a data set by averaging its extreme values. It is defined as the midpoint between the minimum and maximum observations: midrange = (min + max) / 2. The midrange is simple to compute but highly sensitive to outliers and skew, and it is rarely used for rigorous analysis compared with the mean or median.

Example: for the data set 3, 7, 9, 15, the minimum is 3 and the maximum is 15, yielding a midrange of 9.

In acoustics, midrange refers to the middle portion of the audible spectrum. Definitions vary, but midrange is commonly treated as roughly 250 Hz to 2,000 Hz, with some sources extending to about 4,000 Hz. These frequencies carry much of the intelligibility of speech and the fundamental tones of many musical instruments.

A midrange driver is a loudspeaker element designed to reproduce midrange frequencies. It is typically used in multi-way loudspeakers alongside woofers and tweeters, and it is optimized to minimize distortion and frequency response variations within its band.

In other contexts, midrange may refer to any central position between two extremes, or to a midrange setting in consumer electronics, such as midrange equalization. The term is used depending on field and convention.
