To ascertain if the college's scores differ from the national average, computing the mean (average) and standard deviation of the college's SAT writing scores is crucial. The mean showcases the typical score, aiding in comparing it directly with the national average.

Simultaneously, the standard deviation illustrates the dispersion or spread of scores around the mean. If the college's mean SAT writing score significantly deviates from the national average.

It suggests a substantial difference between the college's first-year class scores and the national average. Therefore, analyzing the mean and standard deviation allows for an informed comparison, determining if the college's scores diverge from the national norm.
