Sampling is a process used in statistical analysis in which a group of observations are extracted from a larger population.

The ability of matched sampling and linear regression adjustment to reduce the bias of an estimate of the treatment effect in two sample observational studies is investigated for a simple matching ...

Confirm that larger samples will contain less sampling variation and thus offer a more precise point estimate, and that larger samples are more likely to be closer to the true population value ...

Here is an example of a way sampling could be undertaken without bias. When you have chosen a sampling area, first divide it up into a grid, for instance, having 10 × 10 divisions.

Sampling error, however, is oversimplified when presented as a single number in reports that may include subgroups, poll-to-poll changes, lopsided margins and results measured on the difference.

Although we found bias in samples selected physically, we suspected it also might have played a part in choosing items from a list (for example, picking accounts receivable from a trial balance), an ...

In statistical analysis, a sampling distribution examines the range of differences in results obtained from studying multiple samples from a larger population.
