Measures of central tendency: Median and mode

See the related question below. Divide 21 by 3, since you started out with 3 numbers. This carries the risk of frustrating initiative and enterprise. Accordingly, mode is the best representative value of the series. In any given set, the mean is the average, which isthe total of the numbers divided by how anf numbers there are.

Measures of central tendency: Median and mode

Some data sets do not have a mode because each value occurs only once. Footnotes Source of Support: Also, median is of limited representative character as it is not based on all the items in the series. Now add them up and what do you get?


Definition of mean median and mode?
