OK, I think I have it figured out, can someone check this: 
 
open(IN, "pa5c.dat") || die ("Can't open file $!\n");
        while($line = <IN>){
        chomp($line);
        ++$number;
        ($name, $score) = split(/:/, $line);
        
        $sum = $sum + $score;
        $avg = $sum / $number;
    
        $totd += ($score - $avg)**2;
        $std = sqrt ($totd/ $number);
}
