Will the standard error always be lower than the standard deviation?
No.
Can standard deviation equal standard error?
If n = 1.
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 is the difference between standard error and standard deviation?
Standard error is the difference between a researcher's actual findings and their expected findings. Standard error measures the accuracy of one's predictions. Standard deviation is the difference between the results of one's experiment as compared with other results within that experiment. Standard deviation is used to measure the consistency of one's experiment.
What is Confidence Intervals of Standard Error?
The standard deviation associated with a statistic and its sampling distribution.
The standard deviation of a point estimator is called the?
standard error
When we know the population mean but not the population standard deviation which statistic do we use to compare a sample to the population?
The sample standard error.
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.
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.
In statistics what is SE?
SE is the standard error. it is the standard deviation divided by the square root of sample size. It basically measures how accurately a statistic describes the population.
Will the standard error always be lower than the standard deviation?
No.
Can standard deviation equal standard error?
If n = 1.
What if the standard deviation is negative?
There is a calculation error.

Difference between standard error and sampling error?
Standard error is random error, represented by a standard deviation. Sampling error is systematic error, represented by a bias in the mean.
