**VARPIF (Array,Condition,SumArray)**

- is the set of values.
- is the particular condition value.

## Description

- This function gives the variance based on the entire population which satisfies the given condition.
- In , is the set of values.
- is the particular condition which satisfies the variance values.
- 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.
- 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 VAR function.
- 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 VARPA 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

- VARPIF([12,32,45,10,56],">10") = 268.1875
- VARPIF([14.2,67.3,19.34,20.6,16.02,78.4,54.9],">21") = 92.1355555555556
- VARPIF([14.2,67.3,19.34,20.6,16.02,78.4,54.9],"<21") = 6.517400000000003
