The standard deviation of the population. the standard deviation of the population.
The standard deviation is 0.
T-score is used when you don't have the population standard deviation and must use the sample standard deviation as a substitute.
The standard deviation in a standard normal distribution is 1.
Neither.
the sample standard deviation
Better for what? Standard deviation is used for some calculatoins, variance for others.
The standard deviation is the standard deviation! Its calculation requires no assumption.
The standard deviation of the population. the standard deviation of the population.
The standard deviation is 0.
T-score is used when you don't have the population standard deviation and must use the sample standard deviation as a substitute.
Information is not sufficient to find mean deviation and standard deviation.
It's used in determining how far from the standard (average) a certain item or data point happen to be. (Ie, one standard deviation; two standard deviations, etc.)
Standard deviation is the square root of the variance.
The standard deviation has the same measurement units as the variable and is, therefore, more easily comprehended.
The standard deviation in a standard normal distribution is 1.
Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.
