The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.

The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order, so you may have to rewrite your list first. 

The "mode" is the value that occurs most often. If no number is repeated, then there is no mode for the list.

Mean is average of a data. total upon total event is mean.

Mode is that frequency which occurs the most. First arrange the data in ascending order and then find out which number is occurring the most.That will be the mode of that data.

To find median you need to arrange the data in ascending order and then the middlemost term is the median of that data. If it two numbers are in middle then find the average of that two numbers. This is the required Median of the data.
