The mean is often called the average. To find the mean you take a set of data and calculate the sum of the data, after that you divide the sum by the number of pieces in the set.
The Median
If the total number of observations (n) is an odd number, then the formula is given below:
Median=(n+1)th/ 2 observation
If the total number of the observations (n) is an even number, then the formula is given below:
Median =(n/2)th observation+(n/2 + 1)the observation
The mode is the most frequently occuring observation or value.
Find the mean, median, mode, and range for the following list of values:
13, 18, 13, 14, 13, 16, 14, 21, 13
Solution:
Given data: 13, 18, 13, 14, 13, 16, 14, 21, 13
The mean is the usual average.
Mean = (13+18+13+14+13+16+14+21+13)/ 9=15
(Note that the mean is not a value from the original list. This is a common result. You should not assume that your mean will be one of your original numbers.)
The median is the middle value, so to rewrite the list in ascending order as given below:
13, 13, 13, 13, 14, 14, 16, 18, 21
There are nine numbers in the list, so the middle one will be
(9+1)/ 2=10/2=5
= 5th number
Hence, the median is 14.
The mode is the number that is repeated more often than any other, so 13 is the mode.
The largest value in the list is 21, and the smallest is 13, so the range is 21 – 13 = 8.
Mean = 15
Median = 14
Mode = 13

In the 1800s, nationalist feelings were strong in the hearts of the middle-class Germans. They united in 1848 to create a nation-state out of the numerous German States. But the monarchy and the military got together to repress them and they gained support from the landowners of Prussia (the Junkers) too. Prussia soon became the leader of the German unification movement. Its Chief Minister Otto von Bismarck was the architect of the process with support from Prussian army and Prussian bureaucracy. The unification process was completed after Prussia won wars with Austria, Denmark, and France over seven years time. In January 1871, the Prussian king, William I, was proclaimed the German Emperor in a ceremony held at Versailles.
