DSTDEVP (Array,Field,Criteria)


where,

  • is the range of cells that makes up the list or database
  • shows which column is used in the function and
  • is the range of cells that contains the specified criteria.
    • DSTDEVP() Calculates the standard deviation based on the entire population of selected database entries.

Description

DSTDEVP (Array,Field,Criteria)

  • Standard deviation shows the variation of data points from the average value.
  • If data points are close to mean value, a low standard deviation is observed. If data points are spread out from the mean value, a high standard deviation is observed.
  • A argument can be expressed as "Salary" (a column name) or 3(position of the column).
  • can be any range on the Calci with minimum of one column and at least one row indicating the condition.
  • The columns should not overlap the list of data.

Examples

Consider the following table with Employee details as input to DSTDEVP function.

A B C D
1 Name Age Salary Age
2 <40 >8000 >32
3 >30
4 Name Age Salary
5 John 34 5500
6 Bill 35 6500
7 Clark 29 7000
8 Bob 45 9000
9 Susan 37 4000
10 Jill 45 8000 
=DSTDEVP(A4:C10,"Age",B1:B3) : Calculates the true standard deviation for 'Age' column 
in the range A4 to C10, for the cells with 40>Age>30. 
Returns 4.916588197741686 as a result.
=DSTDEVP(A4:C10,3,D1:D2) : Calculates the true standard deviation for 'salary' 
in the range A4 to C10, for the cells with Age>32. 
Returns 1772.004514666935 as a result.
