In mathematics, an average, or central tendency [1] of a data set refers to a measure of the "middle" or "expected" value of the data set. There are many different de************************ive statistics that can be chosen as a measurement of the central tendency of the data items.

The most common method is the arithmetic mean, but there are many other types of averages.[2]The average is calculated by combining the measurements related to a group of people or objects, to compute a number as being the average of the group.

lectures are not always a good reference.......you should tack your knowledge from the te_t book
