**bobpursley**, Wednesday, October 10, 2012 at 7:46pmput them in order:

2,2,11,18,20,26,27,28

mode: 2 most common

mean: add them, divide by 8: you do it.

median age: find where you can divide the list in two lists of four: well, 18 and 20 are the middle numbers. add them, divide by 2. 19 is the median.

**Kristin**, Wednesday, October 10, 2012 at 7:50pmso the mean is 16.75

The median is 12 right? Because I had to subtract the two middle numbers to get the middle number.

The mode is 2

So would it be the median to represent the ages of the houses?

**Sam**, Tuesday, October 16, 2012 at 2:51pmok stuck again. Got everything else calculated, but why is the median the best choice? is it because 19 is the closest to the mean, 16.75 ? Can you explain??
