If the deviation is small ie if the distribution is packed close to the mean.
No. It is defined to be the positive square root of ((the sum squared deviation divided by (the number of observations less one))
The square of the standard deviation is called the variance. That is because the standard deviation is defined as the square root of the variance.
Standard deviation is the square root of the variance.
The standard deviation of a normal deviation is the square root of the mean, also the square root of the variance.
Standard deviation = square root of variance.
Yes, a standard deviation can be less than one.
In general, a mean can be greater or less than the standard deviation.
No. The standard deviation is the square root of the variance.
Square the standard deviation and you will have the variance.
mean
The deviation is the observed value less the expected value.
Standard deviation = square root of variance.
