Expected value analysis is a statistical technique used to determine the average outcome of a decision by weighing each possible outcome by its probability of occurrence. It helps in making informed choices in uncertain situations, such as investments or risk assessment, by calculating the expected returns or costs associated with different scenarios. The expected value is calculated by multiplying each outcome by its probability and summing these products, providing a single metric that represents the overall potential of a decision. This analysis is particularly useful in fields like finance, economics, and decision-making.

How do i find expected value in a martingale system?
The expected value of a Martingale system is the last observed value.
Difference between mean and expected value?
For a population the mean and the expected value are just two names for the same thing. For a sample the mean is the same as the average and no expected value exists.
What is the expected value of the sum of the number that appears when a pair of fair dice is rolled?
The expected value is 7.
The expected value is what kind of aspect of how probability distribution is characterized?
Expected value is the outcome of confidence of how probability distribution is characterized. If the expected value is greater than the confidence interval then the results are significant.
How much error is expected between the sample mean and population mean?
0. The expected value of the sample mean is the population mean, so the expected value of the difference is 0.
Why is calculating the standard deviation an important part of data analysis?

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.

Information a decision maker need in order to perform an expected-value analysis of a problem?
To perform an expected-value analysis, a decision maker needs to gather information on all possible outcomes of a decision, including their probabilities and associated values or payoffs. This involves identifying the potential scenarios that could result from different choices and estimating the likelihood of each scenario occurring. Additionally, understanding the costs and benefits linked to each outcome will help in calculating the expected value for each option, allowing for informed decision-making. Finally, any uncertainties or risks associated with the outcomes should also be considered.

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.
