Description
- This function gives the standard deviation based on a given sample.
- 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 , are numbers to find the standard deviation.
- Here is required. are optional.
- Instead of numbers we can use the single array or a reference of a array.
- is defined by the formula: Failed to parse (syntax error): {\displaystyle S.D= \frac {\sqrt(\sum(x-\bar{x})}^2{(n-1)} } , where is the sample mean of and is the total numbers in the given data.
- It is calculated using Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle "n-1" } 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

STDEV(V1,V2,...)
Where V1,V2,......are arguments.
It calculates the Standard deviation for a set of values.
- S D is calculated by the "n-1" method.
- The Arguments can be numbers or names, arrays, or references.
- Empty cells, logical values, text, or error values are ignored.
- S D formula is:
Where x is the sample mean average (V1,V2........) and n is the sample size.
