Other differences have to do with nomenclature, notation, and computations. For example, A a measurable characteristic of a population, such as a mean or standard deviation, is called a parameter; but a measurable characteristic of a sample is called a statistic. We will see in future lessons that the mean of a population is denoted by the symbol Î¼; but the mean of a sample is denoted by the symbol x.
Sampling Distribution of the Sample Mean from a Normal Population: n ~ N((x, (x2/n) ( n, a random variable calculated from a sample of size n, is distributed normally with mean, = (x (the mean of the parent population), variance, = (x2/n and standard deviation, = (x/.
