0. The expected value of the sample mean is the population mean, so the expected value of the difference is 0.

The difference between sample mean and population mean is called the?
Sampling Error
What determines size difference between sample mean and population mean?
standard error
When the observed sample mean is close to expected population mean what do you in terms of the null hypothesis?
It depends on whether the hypothesis concerns the mean or the standard error (or variance) or something else.
What would it mean If the sampling error was zero?
The sample consisted of the entire population.
Consider a random sample of size 45 from a population with proportion 0.30 find the standard error of the distribution of sample proportions?

Sampling Error
How much error between sample mean and population mean?
The answer depends on the underlying variance (standard deviation) in the population, the size of the sample and the procedure used to select the sample.
What determines size difference between sample mean and population mean?
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 would a sampling error of zero mean?
The sampling error is the error one gets from observing a sample instead of the whole population. The bigger it is, the less faith you should have that your sample represents the true value in the population. If it is zero, your sample is VERY representative of the population and you can trust that your result is true of the population.
What is the difference between Sampling error and non sampling error?
In stats, a sampling error is simply one that comes from looking at a sample of the population in question and not the entire population. That is where the name comes from. But there are other kinds of stats errors. In contrast, non sampling error refers to ANY other kind of error that does NOT come from looking at the sample instead of the population. One example you may want to know about of a non sampling error is a systematic error. OR Sampling Error: There may be inaccuracy in the information collected during the sample survey, this inaccuracy may be termed as Sampling error. Sampling error = Frame error + Chance error + Response error.
When the observed sample mean is close to expected population mean what do you in terms of the null hypothesis?
It depends on whether the hypothesis concerns the mean or the standard error (or variance) or something else.
How does one calculate the standard error of the sample mean?
Standard error of the sample mean is calculated dividing the the sample estimate of population standard deviation ("sample standard deviation") by the square root of sample size.
What statistical concept is used to explain the natural difference that exists between a sample mean and corresponding population mean?
Random error.
How can one avoid sampling error?
Sampling error cannot be avoided: it is a result of the fact that the sample that you pick for a study will not exactly match the whole population. If there were no variations between the members of the population you would only need to take a sample of size 1 - a single observation would be sufficient.
Is the sampling of error larger when the sample mean is closer to the population mean?
No.
What causes a Sampling error?
a sampling error is o ne that occurs when one uses a population istead of a sample
