Incorrect. You imply a 50/50 split with compensating values, which is absolutely unlikely :S.Originally Posted by Rocky
I'm not going to argue for any side, but think about it: suppose that Ns (or Ss, for that matter) have all an iq of 120 and Ss (or Ns) have all al iq of 80. Suppose also a 50 50 split to render things easy. The average would still be 100 but the averages of the groups would respectively be 80 and 120.
