Question

Mr. Evans wanted to compare the math grades of his 6th grade students and 7th grade students. He displayed the data on dot plots.

Which conclusion can Mr. Evans make?
A.The median grade in 6th Grade is 8 points lower than the median grade in 7th Grade.
B.The median grade in 6th Grade is 3 points lower than the median grade in 7th Grade.
C.The median grade in 6th Grade is 6 points lower than the median grade in 7th Grade.
D.The median grade in 6th Grade is 11 points lower than the median grade in 7th Grade.

Answer 1

Without specific dot plot data for Mr. Evans' classes, we cannot determine the median or the difference in median grades between 6th and 7th grade.

Step-by-step explanation:

Since specific dot plots for Mr. Evans' 6th grade and 7th grade students have not been provided, we cannot determine the exact median grades for each. Therefore, it's not possible to accurately compare the median math grades of the two classes without the actual dot plot data. In a typical scenario, the median can be found by organizing the grades in ascending order and finding the middle value. If there is an even number of data points, the median would be the mean of the two middle numbers. However, without the specific data, we can make no conclusion about the difference in median grades between the two grades.
