Hi!

Could anyone please tell me what's the Default Delta Degrees of Freedom of standard deviation in summarize tool and how can I change it?

Thanks,

Eric

Hi @Eric_Liu_signify,

The degrees of freedom in the Summarize tool's standard deviation calculation uses the population so it is n. If there are nulls, then it is n - nulls. If the Ignore 0's option is selected then it is n - nulls - zeroes.

Thank you,

Here's a macro I built for ST Dev which should allow customization of counting zeros/nulls and DOF. It takes in ONE field so any results have to be appended. It works for me but let me know if you encounter problems.
