: To distinguish that we are calculating the population mean and not the sample mean, we use the Greek lower case letter mu, denoted as µ: An important property of the mean is that it includes every value in yo ur data set as part of the calculation. In a! ddition, the mean is the only measure of central tendency where the sum of the deviations of each(prenominal) value from the mean is always zero. Median In statistics and probability theory, median is described as the numerical value separating the exalted half of a sample, a population, or a take place 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: BestEssayCheap.com
