A numerical measure from a population, such as a population mean, is called ___. Group of answer choicesa parametera samplea statisticthe mean deviation

The correct answer is a parameter.

Explanation:

In statistics, a parameter is a numerical value that summarizes characteristics of a population. It is a fixed value that describes an aspect of a population—like the population mean (denoted as $\mu$) or population standard deviation (denoted as $\sigma$). On the other hand, a statistic refers to a numerical measure that describes a characteristic of a sample drawn from a population. For example, the sample mean (denoted as $\bar{x}$) serves as a statistic that estimates the population mean. Hence, when referring to numerical measures that are derived from the entire population, the term "parameter" is the appropriate choice.

Summary:

• Parameter: A numerical measure from a population.
• Statistic: A numerical measure from a sample.
• Mean Deviation: A measure of the average distance between each data point and the mean.
• Conclusion: The answer is a parameter.
