Quizplus · Accepted Answer

The average score for the group of children is an example of a statistic, not a parameter. A parameter is a measure of a population, while a statistic is a measure of a sample. In this case, the average score of the 3-year-old children is a measure of the sample, not the population of all 3-year-old children.
