In addition, the mean is the only meas! ure of central tendency where the sum of the deviations of all(prenominal) value from the mean is always zero. Median In statistics and face theory, median is described as the numerical value separating the high school half of a sample, a population, or a prognosis distribution, from the lower half. The median of a finite list of numbers can be found by...If you want to get a full essay, order it on our website: OrderEssay.net
