- Sampling error is the error caused by observing a sample instead of the whole population.
- Scientists can reduce sampling error by taking observations from population
<h3>What is a sampling error?</h3>
Sampling error is a kind of experimental error that occurs when statistical characteristics of a population are estimated from a sample.
For example, the difference between a population mean and a sample mean is referred to as sampling error.
Scientists can reduce sampling error by taking observations from population rather than just a subset of the population.

Hope this helps!

<em>Whistling seen as a bad practice by sailors because it challenges the sea is an example of pseudoscience.
</em>
<u>Explanation:</u>
Pseudoscience literally means false science. It claims to be science but it is not scientific at all. It completely fails in a <em>scientific scrutiny </em>and it is not open to evaluation by other experts.
They are just beliefs and practised claimed to be factual even without any proper method used in <em>developing the hypotheses.
</em>
False<em> pseudo scientific claims</em> can be harmful at times. An example is the propaganda against vaccination.
