μ is the symbol for the population mean in statistics.
fyi and related but not necessary for the above answer:
the sample mean is , enunciated by saying "x" bar.
hope this helped.

In statistics, this is the symbol for the "Variance"
The population mean is the mean value of the entire population. Contrast this with sample mean, which is the mean value of a sample of the population.
The mean is typically represented by the symbol ( \mu ) (mu) when referring to the population mean, and by ( \bar{x} ) (x-bar) when referring to the sample mean. These symbols are widely used in statistics to denote the average value of a set of data points.
It means the sum total.
d bar, d with a bar over it

Since this is regarding statistics I assume you mean lower case sigma (σ) which, in statistics, is the symbol used for standard deviation, and σ2 is known as the variance.
No, the sample mean and sample proportion are not called population parameters; they are referred to as sample statistics. Population parameters are fixed values that describe a characteristic of the entire population, such as the population mean or population proportion. Sample statistics are estimates derived from a sample and are used to infer about the corresponding population parameters.
Statistics is the study of collecting , organizing , and interpreting data!
it means the common symbols and expression used in mathematics,geometry and statistics.
Greek letters are used for population parameters. Eg: µ is the population mean English letters are used for sample statistics. Eg: x-bar is the sample mean
N is neither the sample or population mean. The letter N represents the population size while the small case letter n represents sample size. The symbol of sample mean is x̄ ,while the symbol for population mean is µ.
In statistics, µ (mu) represents the population mean, which is the average value of a set of data points in a complete population. It is a key parameter in descriptive statistics and is often used in inferential statistics to make predictions about a larger group based on a sample. The population mean is calculated by summing all values in the population and dividing by the total number of values.
