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 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.
