Cthulhu is thinking about betting on goat ball point spreads. It wants you to figure out some statistics.
Point spread is the difference between scores in a game. So if:
- The New York Nannies scored 10 points and the Buffalo Billies scored 7, the spread would be 3 for the game.
- The Brisbane Bed Bugs scored 11 points and the Yosemite Yolks scores 16, the spread would be 5.
- The average of the spreads for the games would be (3+5)/2 = 4.
You can download the start workbook with the data. It looks like this:
The scores should all be numbers that are zero or more. There are data errors.
Write a program to compute the two counts and the mean, as well as the score differences. Here's the output:
Differences are always positive, or zero.
You can assume that at least some of the data is valid.
