Question
The SAT-Verbal scores of a sample of 300 students at a particular university had a mean of 592 and standard deviation of 73.According to the university's reports, the SAT-Verbal scores of all its students had a mean of 580 and a standard deviation of 110.Which of the following is a statistic?300592580110
Solution
The statistic in this context is the mean of the sample, which is 592. A statistic is a measure that is calculated from a sample of data. It is used to give information about specific aspects of a group of data. In this case, the mean score of 592 is a statistic because it is calculated from the sample of 300 students. The other numbers (300, 580, and 110) are parameters, which are measures that are calculated from an entire population.
