Question 872576: 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.
Thank you in advance Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! Both classes have the same center in terms of the distribution since they both have the same mean; however, class B has scores more spread out from the center since it has a larger standard deviation.
This means the scores in class B vary more and they are further away from the mean.
Class A has scores that are more closer to the mean (and more clustered around it) in relation to class B since it has a smaller standard deviation.
