the anticipated performance of a teacher. The performance of a teacher can be affected by the expectations that the assessor or evaluator has for the teacher being evaluated. If the evaluator has high expectations for the teacher being assessed, there is an increased likelihood of the teacher performing at a higher level than he/she might otherwise; holding low expectations for a teacher can reduce performance levels. Sometimes the opposite impact can occur. Too high expectations can undermine a teacher's confidence, while too low expectations can impel the teacher to strive for greater performance. The same applies with regard to teachers' expectations of students.
In the case of uncertainty, expectation is what is considered the most likely to happen. An expectation, which is a belief that is centred on the future, may or may not be realistic. A less advantageous result gives rise to the emotion of disappointment.
The average amount you make in a specific event or period. Thus, if you have won £7500 in the last 34 tournaments, your expectation is £7500/34 which is £220. Conversly, if you have lost £1500 in the last 34 tournaments, your expectation per tournament is £1500/34 or -£44
Your typical win rate for a particular game, ignoring variance. That is, how much you expect to win (or lose) per hour or per hand over a specific time period. For example in 100 hours play you have won $437, then your expectation is $4.35/hr.
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. 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.
A reference to what a player or the house can statistically expect to win or lose on a given bet or game. For example, the house expectation on a pass line bet a craps is 1.4%. This simply means that the house can expect to win 1.4% of all the money bet on the pass line over the long run. Since the only outcomes are win one unit or lose one unit, a 1.4% expectation means winning 50.7% of the time and losing 49.3% of the time. If the same bet were described for the player, it may be stated by saying the player on average gets 98.6% of his money back on the pass line bet (getting 100% back would be breaking even) or it could be stated that the player has a 1.4% negative expectation on that bet.
Expectation, or â€œexpected valueâ€ of a Variable, refers to the mean value the Variable takes. For example, in a 100 year period, a 1 in 100 year Event is expected to be equalled or exceeded once. This can be defined mathematically.
