Standard deviation is a method that allows an individual to assess the level of dispersion or deviation of the end results from the actual values. It is one of the most common used by almost all industries such as financial and record keeping. Once you have the mean of the values from any given data you can find out its variance and standard deviation so that you can rule out the chances of error from the entire calculation.
Whether you have taken Statistics as your course at the college or you are being delegated a related task at the workplace you should follow a method that is free of any mistakes or deviations. In most cases standard deviation focuses on the population of any given units but it can also be used to find out dispersion of a sample.
No matter what kind of data you have at hand, it is always better to finalize the sources to population as it contains all the elements that can have an increasing or decreasing effect on the calculation. Most expert mathematicians recommend generalizing your findings in relevance to the population rather than the sample.
