If he wants to make his performance sound as good as possible, which measure should he use—the mean, the median, or the mode of his exam grades when he talks about how he is doing?

**Ms. Sue**, Wednesday, October 10, 2012 at 7:43pmFigure out the mean, median, and mode. Which do you think shows his performance most to his advantage?

**Ms. Sue**, Wednesday, October 10, 2012 at 8:02pmWhat did you get for the mean, mode, and the median?

**Kristin**, Wednesday, October 10, 2012 at 8:07pmMean 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.

**Ms. Sue**, Wednesday, October 10, 2012 at 8:17pmThe 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

**Belle**, Wednesday, October 10, 2012 at 8:21pmI thought if I couldn't get it to subtract 81-87? 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!

**Kristin**, Wednesday, October 10, 2012 at 8:23pmI 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.
