Calc: using Randbetween

I want random numbers between minus 3 and plus 3. Is there any difference between:




I've been using the latter but it seems like I'm getting more positives than negatives, in fact twice as many positives. That could be just chance but I've run 720 trials so the sample seems large enough.

Thanks for any help.

I can't find the differences that you mention, find attached a test file RandbetweenTest.ods, use hard recalc [Shit+Ctrl+F9] to recalculate updating Randbetween() values.

Thank you m.a.riosv, for taking the time to construct the spreadsheet comparing the two formulas. It's clear from the results that the two are identical in function and that my experience is just an outlier. Even now, running more trials, I'm seeing results more in line with what would be predicted.

Much appreciated!
