Answer 4

remember this rule when you're in stats :

1) median/IQR : best when u have outliers
2) mean/standard deviation : best when u dont have outliers

Answer 5

I think that movies has the outlier, so I though it was A.

Answer 6

we call median/IQR as robust measures since they give u good results even when u have outliers

Answer 7

look at the given box plots, do u really see any outliers ?

Answer 8

it seems both distributions are uniformly distributed and the most of the observations are lying within the box (middle 50%), right ?

Answer 9

I guess so.

Answer 10

i don't see any outliers
why do u think Movies have outliers ?

Answer 11

Because the end of the Q4 looks kind of far off to me.

Answer 12

yes but its not too far off

Answer 13

how do u decide whether its too far off or not too far off ?

Answer 14

you use that box

Answer 15

Does this mean that they use standard Deviation because there are no outliers? So D?
