Data Sampling

[ManuelRodrigues]

Hi All,

I have around 35000 lines of data and i want to be able to pick a sample of 25 from that. could i please ask if there is a way of doing this say e.g. every 400th incidence?

Thanks

Hi @ManuelRodrigues 

You have two tools that you could use, Sample tool or the Random % Sample tool. If you look at the tool example for the Random % Sample it has some information on the differences between the two tools, as behavior can be different depending on which option you go with

what if the data repeats some lines and i want it to actually be representative of the whole data?

You'd have to put something like a Unique tool prior to the sample selection to filter out any duplicated data
