population mean
True central value
The population mean is the average of all values in an entire population, as opposed to a sample mean calculated from a subset.
In statistics, it represents the true central value that researchers try to estimate: The sample mean approached the population mean as sample size increased.
Symbolized by the Greek letter μ (mu).
