STDEV function

Estimates standard deviation based on a sample




 * STDEV(number1,[number2],...)
 * Number1 - the first number argument corresponding to a sample of a population.
 * Number2 - optional umber arguments 2 to 255 corresponding to a sample of a population. You can also use a single array or a reference to an array instead of arguments separated by commas.
 * STDEV assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the standard deviation using STDEVP.
 * The standard deviation is calculated using the "n-1" method.
 * Arguments can either be numbers or names, arrays, or references that contain numbers.
 * Logical values and text representations of numbers that you type directly into the list of arguments are counted.
 * If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are ignored.
 * Arguments that are error values or text that cannot be translated into numbers cause errors.
 * If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the STDEVA function.
