difference standard deviation of portfolio
the sample standard deviation
yes
The standard deviation associated with a statistic and its sampling distribution.
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.
difference standard deviation of portfolio
the sample standard deviation
The standard error is the standard deviation divided by the square root of the sample size.
yes
we calculate standard deviation to find the avg of the difference of all values from mean.,
The standard deviation associated with a statistic and its sampling distribution.
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.

σ (sigma)
The mean is the average value and the standard deviation is the variation from the mean value.
If repeated samples are taken from a population, then they will not have the same mean each time. The mean itself will have some distribution. This will have the same mean as the population mean and the standard deviation of this statistic is the standard deviation of the mean.
