The question is asking how to compute a sample statistic, which typically involves summarizing or analyzing data from a sample to estimate characteristics of a larger population. This can include techniques such as calculating the mean, median, standard deviation, or proportion.

#### Answer

Mean, variance, and standard deviation of the sample.

The final answer is to compute the mean, variance, and standard deviation of the sample data using the specified steps.

##### Answer for screen readers

The final answer is to compute the mean, variance, and standard deviation of the sample data using the specified steps.

#### More Information

Sample statistics provide valuable estimates of the larger population and are essential in inferential statistics.

#### Tips

A common mistake is neglecting to use n-1 instead of n when calculating variance, which adjusts for sample bias.
