The standard deviation is the standard deviation! Its calculation requires no assumption.
The standard deviation of the population. the standard deviation of the population.
Information is not sufficient to find mean deviation and standard deviation.
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.
Yes
Standard deviation is a measure of the spread of data.
Exactly as in the question: standard deviation!
The standard deviation is a measure of the spread of data.
The symbol for standard deviation is sigma , σ.
Standard deviation of a single event is 0.
No.
