Coke vs. Pepsi: Designing an experiment
Identify a member of your group who claims to be able to tell the difference between
Pepsi and Coke. (Coke Classic, that is; accept no substitutes!) Design and carry
out an experiment to test whether this is true. Remember that one swallow doth not
a summer make: Don't certify your taste-tester just on the basis of one taste. Write down exactly what data you will collect and what you will do with the data before you
start collecting it.

Here was the report of the final Globe poll:
The Globe poll shows the race is as tight as ever, with Buchanan edging into the lead
for the first time at 24 percent, Dole at 23 percent and Alexander at 21 percent.
The rest of the field was well behind: Forbes, 13 percent; Lugar, 5 percent; Keyes,
4 percent; Taylor, 1 percent and Dornan with less than 1 percent. Only 5 percent now
said they were undecided. The polling sample of almost 700 voters has a margin of
error of 4 percent.
The final vote was:
- (1) What do you think "margin of error of 4 percent" means?
- (2) Comment in your journal on your own feelings about use and influence of polling during a political campaign.
