If the standard error of a sample of 48 is equal to 14.25 the standard deviation is equal to?
98.73
Why is standard deviation of a statistic called standard error?
The standard error is the standard deviation divided by the square root of the sample size.
Will the standard error always be lower than the standard deviation?
No.
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.
Is standard deviation and standard error the same?

What is the standard error of the sampling distribution equal to when you do not know the population standard deviation?
You calculate the standard error using the data.
Why is standard deviation of a statistic called standard error?
The standard error is the standard deviation divided by the square root of the sample size.
What is the difference between standard error of mean and standard deviation of means?
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.
True or false a distribution of sample means is normally distributed with a mean equal to the population mean and standard deviation equal to the standard error of the mean?
True.
Why is the standard error a smaller numerical value compared to the standard deviation?
Let sigma = standard deviation. Standard error (of the sample mean) = sigma / square root of (n), where n is the sample size. Since you are dividing the standard deviation by a positive number greater than 1, the standard error is always smaller than the standard deviation.
What symbol is used when the standard error of the sampling distribution when we do not know the population standard deviation is equal to?
When the population standard deviation is unknown, the standard error of the sampling distribution is often represented by the symbol ( s ) divided by the square root of ( n ), which is written as ( \frac{s}{\sqrt{n}} ). Here, ( s ) is the sample standard deviation, and ( n ) is the sample size. This formula provides an estimate of the standard error based on the sample data.
Can a standard deviation of a sample be equal to a standard deviation of a population?
Yes
Is it possible for a standard deviation to be negative?
no it is not possible because you have to take the square of error that is (x-X)2. the square of any number is always positive----------Improved answer:It is not possible to have a negative standard deviation because:SD (standard deviation) is equal to the square of V (variance).
The standard deviation of a point estimator is called the?
standard error
Will the standard error always be lower than the standard deviation?
No.
What if the standard deviation is negative?
There is a calculation error.
