The standard error of the mean, also known as the standard deviation of the mean, helps to determine the differences between more than one sample of information. The calculation accounts for variations that may be present in the data. For example, if yo
One final consideration for calculating standard deviation is whether you are working with a sample or a whole population. While this will not impact the way that you calculate the mean or the standard deviation itself, it does impact the variance. If you are givenallof the numbers in a data...
