| Expectation |
|
[1] A term referring to the amount of you expect to gain on average if you make a certain play. For instance, suppose you put $10 into a $50 pot to draw at a hand that you will make 25% of the time, and it will win every time you make it. Three out of four times, you do not make your draw, and lose $10 each time for a total of $30. The fourth time, you will make your draw, winning $50. Your total gain over those four average hands is $50-$30 = $20, an average of $5 per hand. Thus calling the $10 has a positive expectation of $5. [2] The amount you expect to make at the poker table in a specific time period. Perhaps in 100 hours play, you have won $527. Then your expectation is $5.27/hr. Of course, you won't make that exact amount each hour (and some hours you will lose), but it's one measure of your anticipated earnings.

| Expected Return |
|
The average amount of money paid back on a particular play for a particular bet. The Expected Return (ER) is the Expected Value of a play multiplied by the amount bet. Most commercially available video poker analysis programs, when analyzing a hand, give the ER of each possible play. The program may call those numbers Expected Values, but any qualified statistician will confirm that as a misnomer.

| Expected Value |
|
The statistically projected average per-unit-bet payback of a particular play. Another way of looking at the EV is the average of all possible outcomes for a particular play or game. Most commercially available video poker analysis programs give the Expected Return (ER) of each possible play when a hand is analyzed. Assuming a five coin bet, dividing the ER by five will give the EV. A better technique, however, is to change the bet to one coin and adjust all one-coin payoffs to per-coin values so that the program will give EV directly.
