Two random samples of 27 high school students were shown 25 lines, one at a time, and asked to estimate the length of each one to the nearest 1/2 cm. The students in one group were told the actual length of the line after each guess. The students in the other group were given, in addition, a nickel each time their guess was within 1/2 cm of the correct length. The discrepancy between the student's guess and the actual length was recorded each time.
