Quizplus · Accepted Answer

The mean or percentage derived from a sample is called the sample statistic. The sample error refers to the random error that occurs when estimating a population parameter based on a sample statistic. The standard error is a measure of the variability in the sampling distribution of a statistic, and the parameter is the true value of the population characteristic being studied, which is often unknown. Therefore, the best choice is C, the sample statistic.
