There are three lists of numbers under column A,B,C
Is there any build-in function to determine the stability within change?
For example,
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
On above list, there is no change at all, which is considered very stable.

Does anyone have any suggestions on following lists?
Thanks in advance for any suggestions
Eric
