Out of these Data Points, I am looking for a formula to calculate the following:
False, if the data varies by more than 10% from the maximum value to the minimum value recorded during a 10 data point interval.

 

[Mike Blackman]

Hi,

Are you looking for a 10 point frequency? something like this?

=(MAX(A1:A10)-MIN(A1:A10))/MIN(A1:A10)

Copy down from B5 thru to B30 assusing that your data starts in A1.

 

[CHAGA]

Yes, it is 10 point frequency. I'm looking for an IF formula. If the difference between the MIN and MAX of the 10 point frequency is greater than 10%, then it is FALSE.

 

[Mike Blackman]

Something like this then?

=IF(MAX(A1:A10)-MIN(A1:A10))/MIN(A1:A10)>0.1,"FALSE","")

 

[Scott Huish]

Maybe:

=IF(MAX(A1:A10)<=MIN(A1:A10)*1.1,"")
