How do I calculate sampling error?
To calculate sampling error, you can use the formula: SE = σ / √n, where σ is the population standard deviation and n is the sample size.
What if I don't know the population standard deviation?
If you don't know the population standard deviation, you can use the sample standard deviation as an estimate.
Can you give me an example of this calculation?
Sure! If your sample size is 100 and the sample standard deviation is 15, the sampling error would be SE = 15 / √100 = 1.5.
How does sampling error affect my results?
Sampling error can affect the accuracy of your results; a larger sample size generally reduces the sampling error.
