The mean value.
These terms apply to a set of data: mode: to the most common number (the number that appears most often) median: the middle number mean: The sum of all the data divided by the number of data items present. range: the difference between the largest and smallest values of data

"Mean" is the same as "average". It's equal to (sum of all the items in the group) divided by (number of items in the group).

An average is a sort of middle number.There are three kinds of mathematical average and the unqualified word "average" can refer to any of the three:meanThis is the average that most people would understand by the word "average". It is the sum of the items divided by the number of items.As such it represents the value each of the items would have if they were all the same value.medianIf the items are sorted into order, the median is the value in the middle. (If there are an even number of items, then the mean average of the middle two items). This is the only average of which it can always be said that half the values are above it and half the values are below it.modeThis is the item, or items, that appears the most often or frequently. If all the items have different values then there is no mode average.This is the only average that does not need the items to be numbers, for example, a survey could look at people's favourite chocolate bar - the mode average would indicate that bar which is preferred by most people.

The mean of a set of data is the sum of that data divided by the number of items of data.
Total price of a number of identical items divided by the number of items. Eg the unit price for a 6 pack of cans for 3.00 is 3.00/6 = 0.50 per can.
Average. this is because the typical is what the total divided by the number of items. this is also what the mean (or average) is.
Sort the data items into numerical order (ascending is usual, but descending can be used). The median is the number in the middle: If there are an odd number of items in the dataset, then the median is the middle number, which is the (n+1)/2th item (where n is the number of items in the dataset). Otherwise there is an even number of items in the dataset and the median is the mean of the two in the middle. These items are the n/2th and the (n/2 + 1)th items.
