**PsyDAG**, Tuesday, December 8, 2009 at 10:12amThe value of 4 is much further from the mean than 245, especially in terms of standard deviations (1+ vs. almost -5 respectively). It would be negatively skewed (many scores at the high end, relatively few at the low end).

**Adria**, Tuesday, December 8, 2009 at 1:01pmWith the same mean and st.deviation, but a min of 55 and a max of 330, what would that be? I just need another example explained...thanks.

**PsyDAG**, Wednesday, December 9, 2009 at 2:05pmFigure how many standard deviations (SDs) above and below the mean each extreme is. If they are approximately equal, it is "bell-shaped." If one is significantly further away in terms of SDs, it is skewed in that direction. (You have to decide what is significant.)

There is insufficient data to suggest bimodal.

I hope this helps a little more.
