Verified step by step guidance1
Understand the difference between a parameter and a statistic: A parameter is a numerical value that describes a characteristic of a population, while a statistic is a numerical value that describes a characteristic of a sample.
Identify the population and the sample in the problem: The population is all the gym members of the large gym, and the sample is the 40 gym members surveyed.
Determine what the average workout duration of 52 minutes represents: Since this average is calculated from the sample of 40 gym members, it is a characteristic of the sample.
Conclude that the average workout duration of 52 minutes is a statistic because it describes a characteristic of the sample, not the entire population.
Remember that statistics are used to make inferences about parameters, which are the true values for the entire population.
