Sierra Warner · Answer 1

The mean and median are both 84. (:

88 + 73 + 97 + 76 + 90 + 80 = 504

504 : 6 (because there are 6 numbers given) = 84

^^^ that is how you find the mean.

Focker · Answer 2

To find the mean you: add up all the numbers, then divide by how many numbers there are. So the mean for these numbers would be: 84%

To find the median: You put the numbers in order (From least to greatest), and then find the number exactly in the middle. Here it is an even amount of numbers. No problem, just add the two numbers in the middle and then divide by 2. The answer here is: 84%
