What else can I help you with?
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.
What is the value of negative 9?
negative nine is the value of negative nine
Can A chi-square value can never be negative because?
The chi-squared statistic is calculated by summing (O-E)2/E where E and O are the expected and observed values for some category, and the summation is carried out over all categories. The expected number of observations for any category cannot be negative, and the numerators are squares so each element in the summation is non-negative. Consequently the sum is non-negative.
What is the opposite of the absolute value of negative 30?
The opposite is: negative (the absolute value of negative 30).
Can the expected value of a discrete probability distribution be negative?
Yes it can be negative.
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.
Would you pursue the investment if the net present value is negative?
No. Unless the non-financial value was more than enough to offset the expected financial loss.
Can fisher information be negative?
No, Fisher information cannot be negative. It is defined as the expected value of the squared gradient of the log-likelihood function, which is always non-negative. Since it measures the amount of information that an observable random variable carries about an unknown parameter, a negative value would not make sense in this context.

How do i find expected value in a martingale system?
The expected value of a Martingale system is the last observed value.
What is the value of negative 9?
negative nine is the value of negative nine
What is the mean of a normal distribution?

It also happens to be the mode and median.
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.
