Origin Version (Select Help-->About Origin): Operating System: 7.5
I have constructed some data from another source which is already assembled into log bins with frequency counts. Is there a way to get Origin to recognise this so that I can test it form normal distribution? I am trying to analyse the first and second moments of its distribution.
Once you plot the data in Origin, you could fit it with the Nonlinear Curve Fitting (NLSF) Tool - under the Origin Basic Functions group, there is a LogNomral function. The fit will then return parameters such as peak centroid, width etc.
Import data as histogram
