Noodles and Company tested consumer reaction to two spaghetti
sauces. Each of 70 judges rated both sauces on a scale of 1 (worst)
to 10 (best) using several taste criteria. To correct for possible
bias in tasting order, half the judges tasted Sauce A first, while
the other half tasted Sauce B first. Actual results are shown below
for “overall liking.”
