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.
median is used to refer to the middle number in a group.
Mean, Median, and Mode
Neither.
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.
An outlier pulls the median towards it. For example 1,2,3 Median=2 1,2,3,7 Median=2.5
The median is used when reporting 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.

no it cant bec

Mean, Median, and Mode
Neither.
Can the median and mode be used to describe both categorical data and numerical data
The mean is used for evenly spread data, and median for skewed data. Not sure when the mode should be used.
it is used to find mean<median and mode of grouped data
No. A median makes no sense for categorical data. For example, if you have 10 red cars, 15 blue cars and 20 black cars, what is the median?
The median is 5.The median is 5.The median is 5.The median is 5.
