Question

Rick has collected a sample consisng of 9 measurements. The sample standard deviaon is 3. What is the sample standard error?

1

1.73

3

0.33

Answer 1

The standard error is the population standard deviation.

And the estimate of standard error is given by sample standard deviation divided by square root of sample size.

Where : estimate of standard error / sample standard error.

s : sample standard deviation.

n : sample size.

Here we have,

s = 3   

n = 9

Hence,

sample standard error is, 1.
