A median is a form of average. What we usually think of as an average is more correctly know as the mean. It is the total of the numbers divided by the amount of numbers. The median is the middle number in a set of numbers, when they are listed in numerical order. If you had a list of numbers and one of these was much higher than all the rest, then the mean might not really represent a true reflection of the average as we think of it. Say your numbers were 11, 15, 30, 1200, 4, 19 and 10. Getting the average of those is going to give 184.1429 which isn't really a good representation. The 1200 is causing that value to be considerably higher than most of the numbers. In this case using the median is better. Listing the numbers in order and finding the middle one gives us 15. The median will therefore be 15, which looks more realistic. See the related questions below for more information.

What is the median in mathematical terms?
median is used to refer to the middle number in a group.
What is the difference between the median and the midpoint?
The median is the number in a series that has equal amounts on either side of it. E.g. the median of 15 is 8 because it has seven numbers either side of that value. The midpoint means the same as the median, but median is the most used terminology.
When do you used the measure of central tendency?
Mean, Median, and Mode
Is the range used to compute the median or standard deviation?
Neither.
Is median used for when there is a wide range of numbers?
If the wide range is evenly spread between the very small and the very large (the distribution is symmetric) then there is not much to choose between the median and the mean. If not, the median will have some advantages as a measure of central tendency.
Should The mean or median be used in ordinal data?
The median is used when reporting ordinal data.

What is the measure of central tendency for nominal and ordinal data?
The mode can be used with both kinds of data. The median may be used with ordinal data but great care is required if the median falls between two classes of observations.The mode can be used with both kinds of data.

In deciding which average to use which is most and worst reliable out of mean modal and median?
The mean is used for evenly spread data, and median for skewed data. Not sure when the mode should be used.
