Hi, I have a hash of arrays like this: 

%HoA = (
    A => [2.34, 4.12, 5.32],
    B => [1.42, 8.15],
    C => [8.42, 0.23, 0.45, 6.43],
###...and so on
);

I want to calculate average of each array and display the result like: 

A   3.93
B   4.79
...etc.

I'm not sure how to do this though... that's what I've written so far: Any suggetions? 

my $average;
foreach my $key (keys %HoA) {
    foreach my $value (values %HoA) {
        my @Array = $value;
        $average = average (\@Array);
    }
    print $key, "\t", $average, "\n",
}

sub average { 
    my ($array_ref) = @_; 
    my $sum; 
    my $count = scalar @$array_ref; 
    foreach (@$array_ref) {
        $sum += $_;
    }
    my $av =  $sum/$count;
    return $av; 
}
