FTESTANALYSIS(Array1, Array2, Alpha, NewTableFlag)
where,
Array1 and Array2 - Input range should be one blocks.
Alpha - is a constant and value should be in between 0 and 1.
NewTableFlag - is the TRUE or FALSE.If set as TRUE,the result in new sheet.If NewTableFlag is omitted, it assumed to be FALSE.
F-Test Two Sample for Variances is also knowns as Fisher test. It compares the variances between two groups of data. Variance is a measure of how much the values are dispersed around the mean value.
If Alpha < 0 or Alpha >1, FTESTANALYSIS returns the #ERROR.
F-TEST TWO SAMPLE FOR VARIANCES
Lets see an example in (Column3, Row1)
=FTESTANALYSIS(R1C1:R6C1, R1C2:R6C2, 0.05, TRUE)
It returns the result in new sheet(5Sapce).
=FTESTANALYSIS(R1C1:R3C2, R1C2:R3C2, -1, TRUE)
It returns the #ERROR(Alpha =-1).
