A line segment joining a vertex of a tetrahedron with the centroid of the opposite face is called a median of the tetrahedron. There are four medians, and they are all concurrent at the centroid of the tetrahedron. [10] As in the two-dimensional case, the centroid of the tetrahedron is the center of mass.
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.
The thalweg principle (also known as the thalweg doctrine or the rule of thalweg) is the legal principle that if the boundary between two political entities is stated to be a waterway without further description (e.g., a median line, right bank, eastern shore, low-tide line, etc.), the boundary follows the thalweg of that watercourse.
For the 1-dimensional case, the geometric median coincides with the median.This is because the univariate median also minimizes the sum of distances from the points. (More precisely, if the points are p 1, ..., p n, in that order, the geometric median is the middle point (+) / if n is odd, but is not uniquely determined if n is even, when it can be any point in the line segment between the two ...
Posterior axillary line: A vertical line passing through the posterior axillary fold. Scapular line: A vertical line passing through the inferior angle of the scapula. Paravertebral line: A vertical line corresponding to the tips of the transverse processes of the vertebrae. Posterior median line; Other anatomical lines include:
The median line previously served as an unofficial border between the two sides, but Chinese military aircraft now regularly cross it. China says it does not recognise the line's existence.
the weighted arithmetic mean of the median and two quartiles. Winsorized mean an arithmetic mean in which extreme values are replaced by values closer to the median. Any of the above may be applied to each dimension of multi-dimensional data, but the results may not be invariant to rotations of the multi-dimensional space. Geometric median
Last month, a juvenile gorilla was found onboard a Turkish Airlines flight from Nigeria to Thailand. Officials believe the gorilla was being trafficked for the illegal wildlife trade, finding the ...
