As atherosclerosis is the commonest cause of arteriosclerosis, the two terms are often used interchangeably. Arteriosclerotic heart disease (ASHD), also called coronary artery disease (CAD) or coronary heart disease (CHD), refers to arteriosclerosis of heart or coronary arteries.he most common form of arteriosclerosis is atherosclerosis, in which fat, cholesterol and other substances build up on the inner walls of arteries and form hard structures called plaques or atheromas, which can restrict blood flow.

The central limit theorem states that given a distribution with mean Î¼ and variance Ï2, the sampling distribution of the mean approaches a normal distribution with mean Î¼ and variance , where n is the number of samples.
In statistics, the mid-range or mid-extreme of a set of statistical data values is the arithmetic mean of the maximum and minimum values in a data set, defined as: The mid-range is the midpoint of the range; as such, it is a measure of central tendency.or 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 Î³ 2 from 2.0 to 6.0 as well as from â0.8 to 2.0.
