The standard error is the standard deviation of a sample population. It measures the accuracy with which a sample represents a population.

11 мая 2023 г. · Standard deviation measures how much observations vary from one another, while standard error looks at how accurate the mean of a sample of data ...

To calculate the standard error of the mean, just take the standard deviation of your sample and divide it by the square root of the sample size.

The standard error is calculated by dividing the standard deviation by the sample size's square root. It gives the precision of a sample mean by including the ...

A standard deviation can be obtained from the standard error of a mean by multiplying by the square root of the sample size:
