Data measurements are mean, median, mode, and range.
Mean = add all values, then divide by the total number of values.
Median = the middle value, when the values are arranged in order.
Mode: The value that occurs most often in a set of data.
Range: The difference b/w the greatest and the least.
Let's say most of the students are 11 years, but one is 12 years.  The answer is mode and median. I.e.
(mode) 11, 11, 11, 11, 11, 11, ..., 12. 
(median) 11, 11, 11, 11, 11, ..., 12
They both give the same number (11) for the students' ages.
