The expected value of perfect information is equal to what?
Minimum Expected Regret ( EVPI = Expected Regret of the best solution)
Is the expected value the same as the standard deviation?
No. The expected value is the mean!
What is the meaning of expected value in a probability distribution?
The expected value is the average of a probability distribution. It is the value that can be expected to occur on the average, in the long run.
How do you figure out percentage more?
The percentage change is given by(new value - old value) / old valueFor example, a change from 25 to 27 is (27 - 25) / 25 = 8%Remember that in the answer you get, 1 is equal to 100%. So in the example above, the formula produces .08, which is equal to 8%.
Can expected value be negative?
yes
What is the expected value of the standard normal distribution equal to?
The expected value of the standard normal distribution is equal to the total amount of the value. It is usually equal to it when the value works out to be the same.
The expected value of perfect information is equal to what?
Minimum Expected Regret ( EVPI = Expected Regret of the best solution)
Is the expected value of a discrete random variable equal to the mean of the random variable?
yes?
What is the chi square test used for?
The chi-squared test is used to compare the observed results with the expected results. If expected and observed values are equal then chi-squared will be equal to zero. If chi-squared is equal to zero or very small, then the expected and observed values are close. Calculating the chi-squared value allows one to determine if there is a statistical significance between the observed and expected values. The formula for chi-squared is: X^2 = sum((observed - expected)^2 / expected) Using the degrees of freedom, use a table to determine the critical value. If X^2 > critical value, then there is a statistically significant difference between the observed and expected values. If X^2 < critical value, there there is no statistically significant difference between the observed and expected values.

What is the formula for expected value under certainty?
The formula for expected value under certainty is simply the value of the certain outcome itself, as there is no variability involved. Mathematically, it can be expressed as ( EV = x ), where ( x ) is the guaranteed outcome. In scenarios involving multiple outcomes with probabilities, the expected value is calculated as ( EV = \sum (p_i \cdot x_i) ), but under certainty, ( p_i ) for the certain outcome is 1, rendering the expected value equal to that outcome.
What does it mean if you get a negative number when you calculate for percent error?
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.
Is the expected value the same as the standard deviation?

Suppose a game uses a spinner with five equal sectiona numbered 1-5 to determine the value of tokens given to the player spinning it. What is the expected value of the number of tokens?
To find the expected value of the tokens from the spinner, you calculate the average of the numbers on the spinner. The values are 1, 2, 3, 4, and 5. The expected value is calculated as follows: (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3. Therefore, the expected value of the number of tokens is 3.
How do i find expected value in a martingale system?
The expected value of a Martingale system is the last observed value.
What does 3 quarters value equal?
Depend on what the value is of 1 whole. for example 3/4 of 100 is 75.
