The arithmetic mean is a weighted mean where each observation is given the same weight.
What does mean mean
the mean is an average of a set of numbers
1.The Geometric mean is less then the arithmetic mean. GEOMETRIC MEAN < ARITHMETIC MEAN 2.
The mean of the sampling distribution is the population mean.

Scholars Mate is a 4-move checkmate. It goes like this:(1. e4 e5 2. Bc4 Nc6 3. Qf3 d5 4. Qxf7#)
Fool's Mate 1. g4 e5 2. f3 Qh4 Mate 0-1 Scholar's Mate 1. e4 e5 2. Bc4 nc6 3. Qf3 d6 4. Qxf7 mate 1-0
Right now there are the Quarter Finals: QF1: Czech v Portugal QF2: Greece v Germany QF3: Spain v France QF4: England v Italy The favourites to win the Euros are Spain, but Germany also have a good chance with players like Schweinsteiger and Podolski and Gomez.l
Many beginners sometimes fall for the scholar's mate (or four-move checkmate), which is 1. e4 e5 2. Bc4 Nc6 3. Qf3 g6?? 4. Qxf7#. The quickest way to win the game (although highly improbable, as black would have to make uncomfortable moves and allow himself to be mated) is 1. e4 f6? 2. d4 g5?? 3. Qh5#
The four move checkmate, also known as the "Scholar's Mate" is a very unsound opening. Because it doesn't follow the general rule "never take your queen out too early" or you will lose too much tempo at the beginning. The move sequence is: 1. e2e4, e7e5 2. qh5 (or qf3) nc6 3. bc4, d7d6 and finally, 4. qxf7#. There are many different notations for this opening, but white will always be targeting f7 with a queen and a bishop in the Scholar's Mate.
The opening that has the largest amount of traps in chess is either the Fried Liver Attack in the Two Knights Defense or the Frankenstein-Dracula Variation of the Vienna Game. The Fried Liver Attack has the moves 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.Nxf7! Kxf7 7.Qf3+ Ke6(Ke8?? gets checkmated after 8.Bxd5! Bc5?? 9.Qf7#.) The Frankenstein-Dracula Variation goes somewhat like this: 1.e4 e5 2.Nc3 Nf6 3.Bc4 Nxe4 4.Qh5(if Nxe4? then 4...d5!, which wins a pawn at the least.) 4...Nd6 5.Bb3 Nc6 6.Nb5 g6(if Nxb5??, then Qxf7#!) 7.Qf3 f5 8.Qd5 Qe7 9.Nxc7+! Kd8 10.Nxa8. If you are Black, don't play the Frankenstein-Dracula Variation because you'll end up down four points, or in more practical terms, White would have won a rook for a pawn.
you mean what you mean
Mean is the average.
It mean what you don't what does it mean.
One can't really answer this question. There are several good moves when your opponent first move is e2-e4, e.g. e7-e5 or e7-r6 or c7-c5. None of them will bring you victory by themselves you still have to play better than your opponent.
