I am analyzing particle size distribution data that was already sorted into histogram bins by the lab instrument software. I want to test the size distributions for normality and compare them to each other, but Kolmogorov-Smirnov and other tests available in origin only seem designed to work with raw data that has not yet been binned. Are there any statistical functions designed to work with a dataset like this, or do I need to write a script to un-bin my data in order to run the analyses?

Origin Ver. and Service Release (Select Help-->About Origin): 9.8.0.200
Operating System: Windows 10

Hello Rand,

Sorry, we do not have any built in routines to un-bin data. We do have embedded python functionality, so if you find a Python package that supports un-binning, that could be an option.

Is there any function in Origin that can un-bin the data? I found several tools to bin data, but none to do the reverse.

Yes, Kolmogorov-Smirnov test tool doesn't support the binned data, you might need un-bin your data and then run the analysis.

Thanks,
