The standard deviation of the population. the standard deviation of the population.

Standard deviation in statistics refers to how much deviation there is from the average or mean value. Sample deviation refers to the data that was collected from a smaller pool than the population.

Sure it can. But in the survey business, the trick is to select your sample carefully so that they'll be equal, i.e. a sample that is accurately representative of the population.

the standard deviation of the sample decreases.

If the samples are drawn frm a normal population, when the population standard deviation is unknown and estimated by the sample standard deviation, the sampling distribution of the sample means follow a t-distribution.

The standard deviation of the population. the standard deviation of the population.

If the population standard deviation is sigma, then the estimate for the sample standard error for a sample of size n, is s = sigma*sqrt[n/(n-1)]

the sample standard deviation

Not a lot. After all, the sample sd is an estimate for the population sd.

You use the t-distribution as opposed to the z-distribution when: (1) you are testing a hypothesis about the population mean and the standard deviation is unknown (estimated from the sample). (2) You are constructing a confidence interval for the population mean when the population standard deviation is unknown (estimated from the sample).

The standard deviation if the data is a sample from a population is 7.7115; if it is the population the standard deviation is 7.0396.

The sample standard error.

Standard error of the sample mean is calculated dividing the the sample estimate of population standard deviation ("sample standard deviation") by the square root of sample size.

Standard deviation in statistics refers to how much deviation there is from the average or mean value. Sample deviation refers to the data that was collected from a smaller pool than the population.
