Ms. Sue,
Range: Subtract the lowest number from the highest number.
Median: Arrange the numbers in numerical order. Find the middle number. In this set, the median is the average between the two medians.
Mode: Which number appears the most. Note there is no mode in this group.
Mean: Add the numbers together and divide by 6.

am i right? 
math AIG (Ms.Sue) 
Ms. Sue,
They're right except for the median.
Please rethink that one. 
math AIG (Ms.Sue) 
lidia,
so for median is the answer 9?

math AIG (Ms.Sue) 
Ms. Sue,
No. The median is the middle number.
The median obviously is in the 90s. 
math AIG (Ms.Sue) 
lidia,
is it 91 if wrong please explain how.

math AIG (Ms.Sue) 
Ms. Sue,
You're close. The median is 91.5
97,88,93,90,85,100
85, 88, 90, 93, 97, 100
The two middle numbers are 90 and 93.
90 + 93 = 183
183 / 2 = 91.5
