Can you post your formula? I used this one in A1:A25

=NORMINV(RAND(),0.025,0.3373)

and got these results:

0.470634368

for a little simulation i need to draw random numbers from a normal
distribution with a given mean (0.025) and std dev (0.3373).

Having read some earlier posts i tried =norminv(rand(), mean, std dev).
Apparently, this is not the right formula: it returns regularly values in the
50%s which should not happen from my 2.5% mean. I also found the box-muller
method. How could i transform the random draws from the standard normal
distribution into the ones i need?

Is there another formula i could use?

Thanks a lot in advance
