Quizplus · Accepted Answer

The average time to complete the memory task in this sample is a sample statistic, which is a descriptive statistic that summarizes information about a sample. Population parameters refer to descriptive statistics that summarize information about an entire population, which cannot be directly observed. Inferential statistics, on the other hand, involve making inferences or generalizations about a population based on data from a sample. "Time trial" does not relate to any statistical concept.
