The median is recommended over the mean when data is skewed. However if you are very sure that your data is not skewed at all and has near perfect bell shaped distribution you can use mean. The median on the other hand is said to be the middlemost numerical in an ordered list whether ascending or descending of values. Income is the classic example of when to use the median because it.
I know the difference between the mean and the median. While the arithmetic mean considers all the values in a vector the median value only considers a subset of values. Hence median has been by default the more popular choice to measure central tendency than mean. See answer to When should I use mean vs median.
