The median of a normal distribution with mean μ and variance σ 2 is μ. In fact, for a normal distribution, mean = median = mode. The median of a uniform distribution in the interval [a, b] is (a + b) / 2, which is also the mean. The median of a Cauchy distribution with location parameter x 0 and scale parameter y is x 0, the location parameter.
A median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas.
The Median kingdom probably annexed Mannaea to its territory in the aftermath of the Assyrians' defeat in a battle in 616 BCE. [73] The Median involvement with Assyria from 615 to 610 is marked by three, possibly four, campaigns, each of which concluded with the sack of an important city. The Medes' departure after each conquest suggests a lack ...
The two unusual percentiles at either end are used because the locations of all seven values will be approximately equally spaced if the data is normally distributed [a] Some statistical tests require normally distributed data, so the plotted values provide a convenient visual check for validity of later tests, simply by scanning to see if the ...

L-estimators can also be used as statistics in their own right – for example, the median is a measure of location, and the IQR is a measure of dispersion. In these cases, the sample statistics can act as estimators of their own expected value; for example, the sample median is an estimator of the population median.
