m is an example of which of the following? A population parameter sample statistic population variance mode

The letter "m" typically represents a sample statistic, specifically the sample mean in statistical notation. In the context of statistics:

1. Population Parameter: A value that describes a characteristic of a population (e.g., population mean, population variance).
2. Sample Statistic: A value, like the sample mean ($m$), that describes a characteristic of a sample.
3. Population Variance: A measure of the dispersion of a set of values in a population.
4. Mode: The value that appears most frequently in a data set.

Since "m" is generally used to denote the mean of a sample, the best choice from the given options is that "m" is an example of a sample statistic.
