Exam 4: Central Tendency

If scores are expressed in terms of the amount by which they deviate from a measure of central tendency, the sum of the negative deviations will exactly equal the sum of the positive deviations when deviations are taken about

Question 24

Fifty students take a quiz on which it is possible to earn a score ranging from 0 to 10. Each student writes his or her score on a slip of paper and the slips are then put in a hat and one drawn at random. We will "win" if we guess correctly the score written on the slip. We should guess
