The distribution of SAT verbal scores of University X's incoming freshman class (N=950) has a mean of 475. What is the value for the sum of deviation scores from the mean of this distribution?

  • Stats -

    The sum of deviation scores from any mean is always zero. Since the mean acts as a fulcrum (a balance point), the deviation of scores above the mean (+) always equal the deviation of scores below the mean (-).

    I hope this helps.
