| dimos | WHY NOT 20? |
| dimos | ok, thanks for your interest but I just realized that is cumulative....good luck to all of you anyway |
| ljamieson | lol. I got caught on the cumulative part too. |
| Trev186 | I get the cumulative thing now but my question is how come the frequency distribution is counting up in reverse order? I thought it always had to go in ascending order? This just fools you because you count the opposite way. |
