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.
Population Parameter Definition. Population Parameter is the characteristic of the population. Sample Statistic on the other hand, is a characteristic of the sample. Sample statistic is used to estimate the value of the Population parameter. The value of the statistic will change from one sample to another. So from the distribution of the sample statistic we draw conclusion about the population. A sample statistic need not be always a true value of the population parameter.
