STDEVA()


  • Parameters are set of numbers.
    • STDEVA(), estimates standard deviation based on a sample, including numbers, text, and logical values.

Description

  • This function gives the Standard Deviation based on a given sample including the logical value and text.
  • Standard Deviation is a quantity expressing by how much the members of a group differ from the mean value for the group.
  • It is the used as a measure of the dispersion or variation in a distribution.
  • It is calculated as the square root of variance.
  • In , Parameters are set of numbers to find the standard deviation.
  • Here First parameter is required. From the second parameter are optional.
  • Instead of numbers we can use the single array or a reference of a array.
  • is defined by the formula:

where is the sample mean of x and n is the total numbers in the given data.

  • It is calculated using "n-1" method.
  • This function consider our given data as the sample population.
  • Suppose it consider the data as the entire population, we can use the STDEVPA function.
  • The arguments can be be either numbers or names, array,constants or references that contain numbers.
  • Also we can give the text representations of numbers or logical values , like TRUE or FALSE, in a reference.
  • Suppose the arguments containing TRUE which is evaluate as 1, and the arguments containing FALSE which is evaluate as 0.
  • Suppose the array contains the empty cells and text values like that values are not considered.
  • Suppose the function don't want to consider the logical values and text representations of numbers in a reference, we can use the STDEV function.
  • This function will return the result as error when
   1. Any one of the argument is non-numeric. 
   2. The arguments containing the error values or text that cannot be translated in to numbers.
