there are 15 numbers.

the median is the 8th number.

there are 7 before this number and 7 after this number.

this means dat the 4th number is teh median of the first quartile.

The answer says "there isn't a single number halfway between the smallest number and the median", which is wrong, because there is.

Like I said the 4th number.
