Discrete Data Sets and their Mean, Median and Mode Values
Calculate the arithmetic mean, median and modal values from discrete data sets.
Mean Value
Arithmetic mean value can be calculated by adding together all the values in a set and dividing the result by the number of members in the set. Mean value can be calculated
x_{mean} = (x_{1} + x_{2} + .. + x_{n}) / n (1)
where
x_{mean} = mean value
x_{1} + x_{2} + .. + x_{n }) = set values
n = number of members in the set
Eksample  Mean Value of Data Set
The mean value of set (3,5,2,5,12) can be calculated as
x_{mean} = (3 + 5 + 2 + 5 + 12) / 5
= 5.4
Median Value
The median value can often be a better indication of a set that contains extreme values. The median value can be estimated by
 ranking the data set in ascending order of magnitude
 selecting the middle member of the data set
Example  Median Value of Data Set
The median value of set (3,5,2,5,12) can be calculated by ordering the data in ascending order to
(2,3,5,5,12)
The middle member  and the Median Value  of the ordered data set is 5.
Mode Value
The mode  or modal  value is the most occurring value in a data set.
Eksample  Mode Value of Data Set
The modal value of set (3,5,2,5,12) can be calculated by counting the occurrence of every value in the data set.
As we can see in this limited data set  the modal value  of the data set is 5.
