**VARPA()**

- Parameters are set of numbers.
- VARPA(),calculates variance based on the entire population, including numbers, text, and logical values.

## Description

- This function gives the variance based on the entire population.
- Variance is a measure of dispersion obtained by taking the mean of the squared deviations of the observed values from their mean in a frequency distribution.
- i.e.,variance is a measure of how far each value in the data set is from the mean.
- It is denoted by . The square root of variance is called the standard deviation.
- In , Parameters are numbers based on a population. Here First Parameter is required.From the Second Parameter are optional.
- To find the variance we can use the following formula:

where is the sample mean of and is the sample size.

- Suppose which is indicating all the values are identical.
- When is non-zero then it is always positive.
- This function is considering our given data is the entire population.
- Suppose it should consider the data as the sample of the population, we can use the VARA function.
- The arguments can be either numbers or names, array,constants or references that contain numbers.
- Also we can give the text representations of numbers or logical values , like TRUE or FALSE, in a reference.
- Suppose the arguments containing TRUE which is evaluate as 1, and the arguments containing FALSE which is evaluate as 0.
- Suppose the array contains the empty cells and text values like that values are not considered.
- Suppose the function don't want to consider the logical values and text representations of numbers in a reference , we can use the VARP 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 | |
---|---|---|---|---|---|---|

1 | 40 | 45 | 60 | 24 | 72 | 81 |

2 | 10.21 | 11.65 | 17.81 | 15.02 | 18.18 | 27.41 |

- =VARPA(A1:F1) = 377.555555556
- =VARPA(A1:F2) = 31.4284222222
- =VARPA(12,23,34,45,true) = 242
- =VARPA(12,23,34,45,FALSE) = 250.96000000000004
