Re^3: Excel or Perl for simple statistics?

Ok, so problem seems to be fixed if I use Statistics::Lite module instead...
Do you think it could be associated to the fact that with Statistics::Lite I pass the numbers as array instead of array reference that I was using in Statistics::Basic
My list was:

0.964
0
0
0.94
0.895
0.915
0.775
0.868
0
0.796
0.866
0.819
0
0
0
0
0.794
0.806
0.781
0.807
0.783

.. as array instead of array reference .. I get the same either way and no difference with Excel `#!perl use strict; use Statistics::Basic 'stddev'; my @data = (0.964, 0, 0, 0.94, 0.895, 0.915, 0.775, 0.868, 0, 0.796, 0.866, 0.819, 0, 0, 0, 0, 0.794, 0.806, 0.781, 0.807, 0.783); print stddev(\@data)+0; print "\n"; print stddev(@data)+0; # 0.400791162022762 # excel # STDEVP # Calculates standard deviation based # on the entire population given as arguments. # 0.400791162` [download] poj	[reply] [d/l]

#!perl

my @data = (0.964, 0, 0, 0.94, 0.895,

print stddev(\@data)+0;
print "\n";
print stddev(@data)+0;
