The ages in years of the houses on Kelly’s block are 20, 26, 11, 2, 28, 18, 2, and 27.
Find the mean age of the houses.
Find the median age.
Find the mode.
Which measure(s) would you use to represent the ages of the houses? Explain

mean = add numbers together then divide by how many #s
Median = middle of the numbers
mode is the most frequent number

put 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.

so 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?

I KNEW THAT HEEE

Math  Kristin, Wednesday, October 10, 2012 at 7:54pm
oops! yes I forgot to divide by two! 19 is the median. And would that best represent the ages?

Ok so the median is the best choice ok thanks!

Math  Sam, Tuesday, October 16, 2012 at 2:51pm
ok 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??
