The mean is when you add all the numbers together and divide by how many numbers there are, and yes zero does count. The median is when you put all the numbers together and whichever one is in the exact middle is the median. Sometimes there is an even amount of numbers. If there is you find the middle of those two numbers.

What is the easiest to compute mean median or mode?
The mode is the only one of these measure which can be used with qualitative data: the mean or median are impossible to compute. Also, for a data set consisting of a relatively small number of observations of a discrete variable the mode or modal class is the easiest to find.
How do you compute for the median class?
The median is the number in the middle. Arrange all the scores from smallest to biggest and the middle on is the median if there is an odd number of scores. If there is an even number of scores, find the mean of the two middle numbers and that is the median.
Is the range used to compute the median or standard deviation?
Neither.
Why do we have to compute for the mean median mode and standard deviation?
To obtain a much better, simpler, and more practical understanding of the data distribution.
