Based on the data you have shown. I wrote the code below. However, please be warned that I wrote this off the top of my head and it may not work or even do what I purport it to do.

use strict;
use warnings;

my @array;
my @values;
my $avg;

while(my $line = <DATA>) {
    push @array, $line;
}

foreach my $line2 (@array) {
    my ($time, $val, $err) = split / /, $line2;

    push @values, $val;

    my $tot_val += $val;

    $avg = $tot_val / $#array;
}

my @sort_max = sort {$a <=> $b} @values;
my @sort_min = soft {$b <=> $a} @values;

my $max_val = pop @sort_max;
my $min_val = pop @sort_min;

foreach my $line3 (@array) {
    my ($time, $val, $err) = split / /, $line3;

    if($val == $max_val) {
    print "max: $line3" . "\n";
    } elsif($val == $min_val) {
    print "min: $line3" . "\n";
    }
}

print "avg: $avg" . "\m";
