Question 88365
To find the mean, add up all of the numbers and divide the sum by the number of numbers (which in this case is 6).

{{{Mean=(-8+ -1+ 3+ 5+ 7+ 18)/6=24/6=4}}}


So the mean is 4






To find the median, count off about 3 spaces (just take half of the size of the list, which is 6) from the beginning of the list until you hit the middle. Now count count off about 3 spaces from the end of the list until you hit the middle.

-8,  -1, {{{highlight( 3)}}}, {{{highlight( 5)}}},  7,  18

Since the middle is in between the numbers 3 and 5, add them up and divide that sum by 2.

{{{Median=( 3+ 5)/2=8/2=4}}}


So the median is 4
