**PsyDAG**, Sunday, October 16, 2011 at 11:34pmIf the mode (most frequently occurring score) = 91, at least 2 of the scores = 91. You only need to find one more score. Use the mean.

81 = (x+70+91+91+100)/5

Solve for x.

To check, it should still lead to a median of 91.

81 = 352x/5

81 = 70.4x

x = 1.15??

**PsyDAG**, Sunday, October 16, 2011 at 11:56pmNo, X+352 ≠ 352x

81 = (x + 352)/5

Multiply both sides by 5, then subtract 352 from both sides.
