The back-to-back stem-and-leaf plot below shows exam scores from two different math classes. What is the mode and mean for class A and the range and median for class B?
Possible Answers: A. mode class A = 1 mean class A = 59.4 range class B = 50 median class B = 77 B. mode class A = 61 mean class A = 59.4 range class B = 54 median class B = 78 C. mode class A = 59 mean class A = 56.5 range class B = 54 median class B = 90 D. mode class A = 1 mean class A = 56.5 range class B = 52 median class B = 80
do you want answer and explanation
Explanation.
The mode is basically which number in the set that appears the most often, so if you want you can write it down and see which one shows up the most. To find the mean( also called the average) for class A, you need to add up all the numbers in class A and then divide that sum by how many numbers there are in that class. To find the range in class B you subtract the smallest number from the largest number, and to find the median you order all the numbers in class B from least to greatest and cross them out. The way you do that is you cross the first number out and then the last number and you keep doing that pattern until there is one number left in the middle.
So the anwser would be mode class A = 61 mean class A = 59.4 range class B = 54 median class B = 78
