The problem is to find the median:

1)  8,18,26,4,4,5,  ____

4,4,5,8,18,26

5+8 = 13

IS  13 divided by  2 OR 6   and so doing is the answer

6.5  /   6   /  or  2.1  ?

Hi Breanna - thanks for writing to Dr. Math.

When there are is even number of values in the data, the median is the
average of the middle two values. Since we are averaging TWO numbers
(in your example, the 5 and the 8), we divide by 2. Thus the answer

Median = 13 / 2 = 6.5

is to recall what the median is supposed to tell us. Half the numbers
in the data set are supposed to be less than or equal to the median,
and half the numbers in the data set are supposed to be greater than
or equal to the median.

With a median of 6.5, half the numbers (4, 4 and 5) are less than 6.5,
while the other half (8, 18 and 26) are greater than 6.5.

If we thought that 2.17 was the median, no numbers would be less than
the median and all of the numbers would be greater than the median.
That would make no sense at all. The "average" isn't supposed to be
smaller than ALL of the values in the data.

I hope this helps. If you have any more questions, write back.
