In statistics there are two kinds of means: population mean and sample mean. A population mean is the true mean of the entire population of the data set while a sample mean is the mean of a small sample of the population.
1 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. 2  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.opulation vs Sample. The main difference between a population and sample has to do with how observations are assigned to the data set. 1  A population includes all of the elements from a set of data.
