In her art class, Ms. Walter has 12 students whose ages are listed below:

19, 20, 20, 20, 21, 22, 24, 24, 25, 25, 56, 60

She calculated the mean and the median of their ages. What is the relationship between these two values?

• math -

What mean and median did you find?

• math -

The mean is 28 and the median is 23???

• math -

Why do you think the mean is higher than the median?

• math -

336/12 = 28 right?

• math -

Right.

Note that all but two students are between 19 and 25. The other students are much older. That skews the mean, but doesn't affect the median.

• math -

The answer in the book says the mean is 8 years less than the median. Please explain.

• math -

By your and my calculations, there is 5 years between the median and the mean.

• math -

Thank you! I said the mean is 5 years more than the median.
