The bias of an estimator refers to how reproducible the estimates are over repetitions of the process.

False

A census has no sampling error because there's only one possible sample that can be generated.

True

The reliability of an estimator can be measured in terms of its standard deviation.

False

In a census, nonsampling errors are easier to manage compared to sampling errors.

If the computed estimates from sample to sample are very different from each other, we expect the sampling error to be large.

It is impossible to estimate how varied the estimates are from sample to sample and how close they are, on average, to the parameter of interest.
