What are mean and variance of negative binomial distribution by conclusion?
what is meant by a negative binomial distribution what is meant by a negative binomial distribution
Can the mean of probability distribution be a negative number?
Yes.
When your sample data is all negative values how can you convert it for use on a normal distribution?
The data from a normal distribution are symmetric about its mean, not about zero. There is, therefore nothing strange about all the values being negative.
What is the definition of skewed distribution?
Probability distribution in which an unequal number of observations lie below (negative skew) or above (positive skew) the mean.
If the mean of a normal distribution is negative what is the varience?
The variance is always positive. The variance is not directly related to the sign (nor magnitude) of the mean.

Can a normal distribution have a negative mean?
Yes. If much of your data has negative values, it's likely that the mean will be negative, too.
Can the mean of probability distribution be a negative number?
Yes.
Can the F distribution be negative?
The F distribution can't be negative.
What does a negative kurtosis mean?
It means distribution is flater then [than] a normal distribution and if kurtosis is positive[,] then it means that distribution is sharper then [than] a normal distribution. Normal (bell shape) distribution has zero kurtosis.

The variance is always positive. The variance is not directly related to the sign (nor magnitude) of the mean.
The F-distribution is symetrical around mean zero True or False?
The F-distribution is either zero or positive, so there are no negative values for F. This feature of the F-distribution is similar to the chi-square distribution. The F-distribution is skewed to the right. Thus this probability distribution is nonsymmetrical.
How do you determine if the critical z value of a standard normal distribution is positive or negative?
Use the context: if the variable should be greater than the mean then z is positive and if less than the mean, it should be negative.
Can The standard deviation of a distribution be a negative value?
No. The standard deviation is not exactly a value but rather how far a score deviates from the mean.
Can the expected value of a discrete probability distribution be negative?
Yes it can be negative.
