**PsyDAG**, Monday, April 23, 2012 at 12:43pmAren't all of the tests missing?

Half of the scores are above and below 85 (median). More than one of the scores are 90 (mode).

Mean (83) = Σx/n = Σx/5

Σx = 83 * 5 = 415

With two scores at the mode, 415 - 180 = 235 for the remaining three scores. If one score is on the median (85), this would leave 150 for the remaining two scores, both below the median (85). If one was 84, then the other would be 150-84 = 66
