STDEVIF (Array,Condition,SumArray)


  • is the set of values.
  • is the particular condition value.

Description

  • This function shows the Standard Deviation of the given set which satisfies the given condition.
  • In  ,  is the set of values.
  •   is the particular condition which satisfies the Standard deviation value.
  • Standard Deviation is the quantity expressed by, how many members of a group differ from the mean value of 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.

  is defined by the formula:

 

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

  • It is calculated using   method.
  • This function is considering our given data is the sample of the population.
  • Suppose it should consider the data as the entire population, we can use the STDEVP function.
  • The arguments can be be either numbers or names, array,constants or references that contain numbers.
  • Suppose the array contains text,logical values or empty cells, like that values are not considered.
  • When we are entering logical values and text representations of numbers as directly, then the arguments are counted.
  • Suppose the function have to consider the logical values and text representations of numbers in a reference , we can use the STDEVA 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

Examples

  1. STDEVIF([19,17,23,10,12,15,22],">10") = 4.1952353926806065
  2. STDEVIF([22,24,27,32,10,18,45,43,55,14],"<15") = 2.8284271247461903
  3. STDEVIF([22,24,27,32,10,18,45,43,55,14],">15") = 13.046619704516788
