Is standard deviation same as standard error?
From what ive gathered standard error is how relative to the population some data is, such as how relative an answer is to men or to women. The lower the standard error the more meaningful to the population the data is. Standard deviation is how different sets of data vary between each other, sort of like the mean. * * * * * Not true! Standard deviation is a property of the whole population or distribution. Standard error applies to a sample taken from the population and is an estimate for the standard deviation.
What symbol is used for the standard deviation when it is a sample statistic?
σ (sigma)
You take an SRS of size n from a population that has mean 80 and standard deviation 20 How big should n be so that the sampling distribution has standard deviation 1?
400
If quartile deviation is 24. find mean deviation and standard deviation?
Information is not sufficient to find mean deviation and standard deviation.
What is the relationship between standard deviation and variance?
Standard deviation is the square root of the variance.
Is the Symbol for the population standard deviation?
A lower case s is the symbol.
Population standard deviation symbol?
σ sigma
What is the symbol for standard deviation?

What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
Is population standard deviation the same thing as absolute standard deviation?
No.
Can a standard deviation of a sample be equal to a standard deviation of a population?
Yes
What is the standard deviation of 157 160 161 172 165 149?
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.
What is the statistic that is used to estimate a population standard deviation?
the sample standard deviation
How do you pronounce standard deviation symbol?
Sigma
The standard deviation of the distribution of means is also known as the population standard deviation?
Yes.
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)]
The population standard deviation is 100?
It can be.
