Mean - The mean, or average, is the sum of all the list divided by the number of items in the list.
Remember: The mean is not a value from the original list, it is a common result and the result will not necessarily be from the original numbers!
Median - The median is the numeric value separating the lower half of the list from the higher half. In other words it is the number in the middle of the list when in numerical order.
Mode - The mode is the value that occurs most frequently in a list.
Range - The range is the difference between the highest value and the lowest value in a list.
Central Tendency- This is the average (mean, median and mode) of a distribution of information.
