Simpson's Paradox - a Test

This is a very quick test of your ability to make sense of some fairly simple data.

Every year Summerfield Junior High awards a prize to the member of its quiz team who has the highest average score over a series of games against rival schools Winterfield High and Springpark High. This year Bart and Lisa are Summerfield's highest scoring quiz team members. Your job is to work out as quickly and efficiently as you can which of the two should be awarded the prize.

Here's some sample data:

Opponent: Winterfield High
	Bart	Lisa
Games Played	100	100
Total Score	1000	100
Average	10	1

Opponent: Springpark High
	Bart	Lisa
Games Played	100	100
Total Score	1000	100
Average	10	1

Hopefully you find this very easy. Bart has a higher average against both schools and a higher overall average (he's played 200 games with an average score of 10, Lisa has played 200 games with an average score of 1). So Bart wins the prize. That's all you have to be able to work out (though obviously the data is going to be a little more challenging). To begin, press the button below, which will reveal the data and start the timer. (Then once you've worked out whether Bart or Lisa has the highest overall score, make your selection, and press Submit.)
