Question

Two classes took a statistics test. Both classes had a mean score of 73. The scores of class A had a standard deviation of 5 and those of class B had a standard deviation of 10. Discuss the difference between the two​ classes' performance on the test

Answer 1

Answer:

Class B performance on the test is good as compared to that of Class A.

Step-by-step explanation:

We are given that two classes had a test mean score of 73 each.

The scores of class A had a standard deviation of 5 and class B had a standard deviation of 10.

From this we can make inferences that since scores of class B had a standard deviation which is more than that of class A which implies that scores of class B shows a higher variation in their test scores means they are not centered around the mean and are farther from the mean value of score.

On the other hand, class B shows a lesser variation in their test scores as they are clustered around the mean value and depicts consistency in their test scores.

Both the classes have mean score mean they have same centers in terms of distribution of their test scores.
