Alternatively, it is another name for the first derivative. The hessian matrix is the matrix of the second derivatives.
z-score of a value=(that value minus the mean)/(standard deviation)
A negative z score is a value that is less than the mean value.
The standard deviation.z-score of a value=(that value minus the mean)/(standard deviation)
Charts typically show and list the area to the left of the Z-Score value. To find the area to the right, just subtract the Z-Score value from 1; e.g. if the Z-Score value is .75 then take 1-.75 = .25.
Provided the distribution is Normal, the z-score is the value such that the probability of observing a smaller value is 0.25. Thus z = -0.67449
A score is 20
It is not necessarily a 'Biblical' meaning as a score is an accepted number in mathematics. One score = 20, so therefore threescore = 60
A z-score of 0 means the value is the mean.

z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
z-score of a value=(that value minus the mean)/(standard deviation)
z-score of a value=(that value minus the mean)/(standard deviation)
z-score of a value=(that value minus the mean)/(standard deviation)
A negative z score is a value that is less than the mean value.
