Is there an easy way to get the FWHM of a normal distribution curve from Distribution function ?

[#1]

Dear JMP community,

Is there an easy way to get the FWHM(full width at half maximum) of a normal distribution curve from Distribution function ?

Apparently, the FWHM of a Gaussian is about 2.355 * sigma. So once you have an estimate of sigma from the Gaussian fit you are done (use 'Analyse > Distribution' then go to the 'Continuous Fit > Normal' option from the red triangle).
