The overlapping depends a lot of the size of the sample. To find the standard deviation of each population is easy:

use Statistics::Basic qw(stddev); #generate a lot of random numbers, by the preferred way, ie: for (1..1000){ $number1= int(rand(100000000)); push @listofnumbers1, $number1;} my $stddev1 = stddev(@listofnumbers1); #repeat the process push @listofnumbers2, $number2; my $stddev2 = stddev(@listofnumbers2);
