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.
