in reply to Frequency table and frequencypolygon

The frequency_distribution_ref() method of Statistics::Descriptive looks like it fits the bill for your frequency table.

You'll need to provide more information about your frequency polygon. There's lots of modules for creating graphics: what format did you want? do you have special requirements? what else can you tell us that would help us help you?

    I am up to here now:
    use Statistics::Descriptive; $stat = Statistics::Descriptive::Full->new(); $stat->add_data(1.45,3.29,1.63,4.31,6.78,0.44,0.51,6.91,3.32,8.59,3.63 +,-5.30,0.61,6.31,0,7.83,-0.76,-3.33,4.24,6.90,2.40,6.27,2.01,1.56,0.4 +5,3.86,-3.49,2.54,1.66,2.19,0.57,1.78,5.22,2.35,0.82,-0.49,1.59,-3.45 +,-3.27,-0.16,3.86,0.29,9.63,3.38,3.43,1.54,-0.61,-4.28,1.20,-2.94,2.9 +0,6.17,0.35,2.20,7.31,11.63,6.83,-0.25,17.28,-4.45,5.01); %f = $stat->frequency_distribution(5); for (sort {$a <=> $b} keys %f) { print "key = $_, count = $f{$_}\n"; }

    and I get:
    key = -0.784, count = 8 key = 3.732, count = 34 key = 8.248, count = 15 key = 12.764, count = 3 key = 17.28, count = 1

    How can I plot it now? I want something like: +jpg
