I presume you're doing mean, median, and mode. Mean is average (add up and then divide by how many #s you have), mode is the one that appears the most, and for median you line them up from smallest to biggest and the one in the middle is the median. If there are an even number of numbers in the line and hence no middle number, you average the two in the middle (add and then divide by 2). The median is useful when outliers throw off the mean and sometimes is more indicative of what's really going on.

According to dictionary.com...
Arithmetic, Statistics. the middle number in a given sequence of numbers, taken as the average of the two middle numbers when the sequence has an even number of numbers: 4 is the median of 1, 3, 4, 8, 9.

The median is the middle number - so you line them up in order from lowest to highest and it is the number in the middle, or if there are 2 numbers in the middle it is the mean of these 2 numbers.
Eg: Median of 1,2,3,4,5,6,7,8,9 would be 5
Median of 1,2,3,4,5,6,7,8,9,10 would be (5+6)/2 = 5.5
(When you add up ALL the numbers and divide by the total amount of numbers it is called the MEAN, not median.

I will quote wikipedia to break the tie. " The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one."

median equals average. add up all the numbers in the list and divide by the amount of numbers.

you put the numbers in order from lowest to highest and count to the middle number. if there are two you take the average of them.
