A sampling error can occur with a simple random sample if the sample does not end up accurately reflecting the population it is supposed to represent.

Serious polling requires careful data collection and careful adjustment. It doesn't mean much to say your poll is a "probability sample" when your nonresponse rate is 90 percent.

While representative sampling is one of the most effective methods used to reduce error, it is often not enough to do so sufficiently on its own.

The weighting procedure also accounts for the fact that respondents with both landline and cell phones have a greater probability of being included in the combined sample and adjusts for household ...

We investigated sampling and non-sampling errors for size measurements (straight carapace length, straight carapace width, and mass) of hatchling Flatback Turtles, Natator depressus, from two study ...

Designers must understand the frequency-domain mechanisms of jitter-induced sampling errors to achieve the optimal system and data converter performance.
