**STDEVP()**

- Parameters are set of numbers.
- STDEVP(),calculates standard deviation based on the entire population

## Description

- This function gives the standard deviation based on a entire population as the the given data .
- 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 , Parameters are set of numbers to find the Standard Deviation.
- Here First Parameter is required. From the second parameter are optional.
- Instead of numbers we can use the single array or a reference of a array.
- is defined by the formula:

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

- It is calculated using method.
- This function is considering our given data as the entire population.
- Suppose it should consider the data as the sample of the population, we can use the STDEV function.
- For huge sample sizes the functions and are approximately equal values.
- The arguments can 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 STDEVPA 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

A | B | C | D | E | F | G | |
---|---|---|---|---|---|---|---|

1 | 87 | 121 | 427 | 390 | 110 | 54 | 32 |

2 | 2 | 2.4 | 3.7 | 14.9 | 28 | 198 | 154.1 |

3 | 9 | -4 | -29 | 38 | 101 | 19 | 45 |

- =STDEVP(A1:E1) = 149.0597195757
- =STDEVP(A2:G2) = 76.31463871127
- =STDEVP(A3:E3) = 44.58250778015
- =STDEVP(0,2,8,10,11.7,23.8,32.1,43.7) = 14.389530699435
