Question

A particular country has 40 total states. If the areas of 20 states are added and the sum is divided by 20​, the result is 210 comma 918 square kilometers. Determine whether this result is a statistic or a parameter. Choose the correct answer below. A. The result is a statistic because it describes some characteristic of a population. B. The result is a statistic because it describes some characteristic of a sample. C. The result is a parameter because it describes some characteristic of a sample. D. The result is a parameter because it describes some characteristic of a population.

Answer 1

Answer: B. The result is a statistic because it describes some characteristic of a sample.

Explanation: Statistics and Parameters are similar in that they are both numerical values that show the characteristic of a given group.

They differ in that the group whose characteristics they show differ. Statistics describe the characteristic of a sample while Parameters describe the characteristic of a population. In this case if the characteristic being measured is the whole country or all the 40 states, the value would be a parameter.
