as root calculates the error?
the error it shows is absolute error or a percentage error

Looking at the printout: “statistical error” = “standard deviation” = sqrt(“bin content”)

Hi @nick,

According to the implementation of TH1::Print(), the error here is printed as returned by GetBinError() (see documentation here), which is aligned with the reply from @Wile_E_Coyote.

Cheers,
