Excel provides useful statistical functions for finding the variance of a data set. In general, these functions variance memorized a set of values called a worksheet range and then calculating the expected.
A detour to remind readers that it is only a common measure to describe the spread of observations in a distribution. A variation is another statistical measure, the relative standard deviation. A deviation is equal to the square of the standard deviation.
Variancea sample of VAR
If the record is to work with a sample, and you do not want to include logical values or text from the amount in the calculation, use the VAR. For example, if you can open a new manufacturing process that should result in increased productivity and a series of data on the number of pieces per day, the variance of the sample. The VAR function uses the following syntax:
= VAR (data set range)
Variance of a samplewith VARA
If the record is an example, but you want to include logical values or text in the calculation, use the VARA function. Excel includes cells containing the logical value TRUE as 1 and cells containing text or FALSE 0 The VARA function uses the following syntax:
= VARA (data set range)
Variance of a sample with VARP
If the record is to work with people, and you do not want to include logical values or textthe amount of calculation, use the VARP. The variance function uses the following syntax:
= VARP (data set range)
Variance of a population with the VARPA
If the record is a population, but you want to include logical values or text in the calculation, use the VARPA. The VARPA uses the following syntax:
= VARPA (data set range)
One last note about the topic Data Range in September
Another tip: you can have moreWorksheet as the set of interval data is sufficient argument for the use of variance functions. For example, if you were to calculate the variance of a sample of VAR and had the data in different ranges saved worksheet, your VAR as follows:
= VAR (B1: B: 10, B101: B110, B200)
