Question

Ari’s teacher says he may have his report grade based on either the mean or the median of his last six test scores.

Answer 1

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%

Answer 2

Answer: The Mean

The mean is when you add up all of those grades and divide by the amount of exams.
