a
what can you say about the class? Include an interpretation that is specific to
grades in a class.

Answer 1

A large range shows that the grades of the class are feasible while a small standard deviation shows that the standard deviation is closer to the mean.

The range is defined as the difference between the largest number and the lowest number in a set of data. They measure the level of feasibility of a set of data to be analyzed.

Standard deviation is an absolute value that depends on the mean. The lower standard deviation shows that the standard deviation is closer to the average data of the class.

Based on the explanation, we can conclude that a large range shows that the grades of the class are feasible while a small standard deviation shows that the standard deviation is closer to the mean.
