Sample standard deviation?
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.
What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
Can a standard deviation of a sample be equal to a standard deviation of a population?
Yes
How do you calculate sample standard deviation?
Here's how you do it in Excel: use the function =STDEV(<range with data>). That function calculates standard deviation for a sample.
Can a standard deviation of a sample be less than a standard deviation of a 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.
How do i find sample standard deviation from population standard deviation?
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)]
How do you find the sample size when given the standard deviation and the mean with a sample value?
You cannot from the information provided.
What is the sample standard deviation of 27.5?
A single observation cannot have a sample standard deviation.

What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
Can a standard deviation of a sample be equal to a standard deviation of a population?
Yes
How does one calculate the standard error of the sample mean?
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.
What happens if you estimate population standard deviation with the sample standard deviation?
Not a lot. After all, the sample sd is an estimate for the population sd.
What is the statistic that is used to estimate a population standard deviation?
the sample standard deviation
Does the distribution of sample means have a standard deviation that increases with the sample size?
No, it is not.
How do you calculate sample standard deviation?
Here's how you do it in Excel: use the function =STDEV(<range with data>). That function calculates standard deviation for a sample.
What is a standard sample deviation?
Milimetres and Centimetres.
