Jack has the following scores on exams in his math class.
81, 87, 93, 89, 61, 81
If he wants to make his performance sound as good as possible, which measure should he useāthe mean, the median, or the mode of his exam grades when he talks about how he is doing?

Math help! 
Ms. Sue,
Figure out the mean, median, and mode. Which do you think shows his performance most to his advantage?

Math help! 
Kristin,
The mean?

Math help! 
Ms. Sue,
Nope.

Math help! 
Kristin,
It would have to be the median?

Math help! 
Ms. Sue,
What did you get for the mean, mode, and the median?

Math help! 
Kristin,
Mean 82
Median 3
Mode 81
The median? But I really do not understand it because it is such a low number? I am sorry I am trying to understand. 
Math help! 
Ms. Sue,
The median is not 3. The median is the middle number of a set.
61, 81, 81, 87, 89, 93
The middle of this set is the number between 81 and 87 = 84 
Math help! 
Belle,
I thought if I couldn't get it to subtract 8187? So I just put 81, 82, 83, 84, 87? Then go from there to get my middle? ok And the best sounds like it would difinietely be 84. I am going to go back to my chapter and see what I forgot. Thanks Ms. Sue!

Math help! 
Kristin,
I got the same thing 3. our teacher we thought said to subtract the two middle and then divide it by two to get the median. We are confused.

Math help! 
Ms. Sue,
You're welcome, Belle/Kristin.
