Question

What is the difference between a sample statistic and a population​ parameter?

a. a sample statistic is frequently impractical or impossible to find for large​ samples, however a population parameter is often easier to find and provides a reasonable approximation to the sample statistic.
b. a population parameter is frequently impractical or impossible to find for large​ populations, however a sample statistic is often easier to find and provides a reasonable approximation to the population parameter.
c. a sample statistic is a subset of a population parameter.
d. a population parameter is a subset of a sample statistic.
e. there is no difference between a sample statistic and a population parameter?

Answer 1

The answer is B. Population parameter involves examining everyone who fits the description you are looking at, which is simply impractical if you’re surveying a large number of people. Studying a smaller sample of subjects is generally more doable but by using inferential statistics, it is possible to arrive at a close approximation to the population parameter.
