Answer 6

I thought it was against rule to repeatedly post the same thing without waiting. I waited and bumped it several times, so I on't think I'm doing anything wrong.

Answer 7

See? *short period of time*. It has been a long time.

Answer 8

Well I'm not sure. Let's ask @ganeshie8 ;)

Answer 9

Sure. All I'm saying is, I did nothing wrong. I ask for help, you get mad, and bombard me saying I did something wrong.

Answer 10

I didn't get mad. Did you see me get mad, @ganeshie8 ?

Answer 11

this looks like stats, im still searching for the question in above comments, whats the exact question that you're stuck on ?

Answer 12

If we could graph it would could easily see what the center would be..

Answer 13

nvm, found it

Answer 14

Thats what I'm stuck on, I don't really know how to graph it with this info. i just plot it down on the points just like that?

Answer 15

here is the rule :
use mean if you have outlisers in the data
use median in all other cases

Answer 16

do u see any outliers in the Rome data ?

Answer 17

I don't really think there are outliers... does 21 count as an outlier?

Answer 18

Notice that the Q3 is just 7.5, so any data around 20 is most likely an outlier

Answer 19

So they both have outliers, which mean the answer is A?

Answer 20

i gave u wrong rule earlier

Answer 21

here is the the corrected rule :
use median if you have outlisers in the data
use mean in all other cases

Answer 22

Oh... So it is B?

Answer 23

since you have outliers in both data, you use the robust central measure `median`

Answer 24

Yup !

Answer 25

use medain for both

Answer 26

Thank you! :D
