Standard Deviation - Group By

Hi Friends

I have these values

3690.9

3699.0

3708.42

3745.28

3755.2

3964.27

4178.79

And I’m trying to calculate de Standard Deviation

I’m not a Statistician, but my value differs from searching on the internet.

I had used Excel and the Excel gives me a value of 170,33

And chatgpt also gives me 170,00

But Knime, in group by node, gives me 183,97

Why is different?
