The F.TEST function in Excel is a statistical tool that allows users to compare the variances of two data sets. It calculates the probability that the variances of these two data sets are equal, thus helping users determine if the difference between them is significant or simply due to chance. To use the F.TEST function, simply select the two data sets you want to compare and enter the formula “=F.TEST” followed by the cell references of the two data sets. This function is particularly useful in data analysis and decision-making processes, as it provides a quantitative measure of the similarity or difference between two sets of data.
Returns the result of an F-test, the two-tailed probability that the variances in array1 and array2 are not significantly different.
Use this function to determine whether two samples have different variances. For example, given test scores from public and private schools, you can test whether these schools have different levels of test score diversity.
Syntax
F.TEST(array1,array2)
The F.TEST function syntax has the following arguments:
Array1 Required. The first array or range of data.
Array2 Required. The second array or range of data.
Remarks
The arguments must be either numbers or names, arrays, or references that contain numbers.
If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
If the number of data points in array1 or array2 is less than 2, or if the variance of array1 or array2 is zero, F.TEST returns the #DIV/0! error value.
Example
Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.
Data1 | Data2 | |
6 | 20 | |
7 | 28 | |
9 | 31 | |
15 | 38 | |
21 | 40 | |
Formula | Description | Result |
=F.TEST(A2:A6,B2:B6) | F-test for the data sets in A2:A6 and B2:B6. | 0.64831785 |
