Standard Deviation (STDV) is the variation of data about an average of the collected data. It provides one with an expectation of results of experimental process provided the data points are all collected in the same way

Explanation:

As mentioned above, Standard Deviation (STDEV) is the variation of data about the average of data all collected in the same way. A simple example is given a random collection of pennies and asked to determine the mass value weights using a 4-digit top loader analytical balance, one might get the following measurements...

m_1 = 2.3578 grams
m_2 = 2.3062 grams
m_3 = 2.2951 grams
m_4 = 2.3325 grams
m_5 = 2.2897 grams

The following is a common calculation for determining STDEV although most spreadsheet programs have this function included in the program.
