DSTDEVP(database, field, criteria)
where,
- is the range of cells that makes up the list or database
is the range of cells that makes up the list or database- shows which column is used in the function and
shows which column is used in the function and- is the range of cells that contains the specified criteria.
is the range of cells that contains the specified criteria.DSTDEVP() calculates the standard deviation of a population, based on the entire population by using data in a database column that matches the specified condition.
Description
DSTDEVP(database, 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.
| Name | Age | Salary | Age |
| <40 | >8000 | >32 | |
| >30 | |||
| Name | Age | Salary | |
| John | 34 | 5500 | |
| Bill | 35 | 6500 | |
| Clark | 29 | 7000 | |
| Bob | 45 | 9000 | |
| Susan | 37 | 4000 | |
| 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.
