When you want to know the piece of data that falls right in the middle.
You would use the median if the data were very skewed, with extreme values.
I use it in class when looking at my student's scores... Often I look at mean, median, and mode to decide to reteach a concept or not.
MEAN
You would use the MEDIAN function. If the cells with your data were from A2 to D50, then the function would be:=MEDIAN(A2:D50)
To find the Median in Math, if you have two numbers, the Median will be the middle number. If you had 1 and 10 to find the Median from, the answer would be 5. Also, if the highest number is not an even number, you use a point. Example: 1 ----- ? ----- 9 ? = 4.5. That solve your answer?

The median.
The median is the 50% percentile.
mean is the average of numbers in the data set mode is the most frequently occurring value in a data set and median is the middle number of the data set so you would use mean
Technically, you cannot find a median if you have only two numbers, so it would be more reasonable to use an average instead.
You would use median instead of mean because the median doesn't find the average, it finds the middle value. Even if its not the middle of the range (the exact middle value between the lowest number and the highest number) it still is near to the middle value. The mean finds the average of all the numbers, like when a teacher average's her students' grades. Median is better to use when finding the middle value, not the average.
There would be no median.
