To compare:statistics and parameters.
Answer to Problem 25HP
A statistic is a measure that describes a characteristic of a sample, whereas, a parameter is a measure that describes a characteristic of a population.
Explanation of Solution
Given information :
To compare and contrast the following:
Statistics and parameters.
A statistic is a measure that describes a characteristic of a sample.
A parameter is a measure that describes a characteristic of a population.
A statistic usually varies from sample to sample but a parameter does not changes as it represents the entire population. For example, in a basketball tournament, the average height of all the players participating can be measured by measuring the heights of a random sample of players at the tournament. The mean height of the sample is a statistic; and the actual height of the players at the tournament is a parameter.
