Q: What part of an experiment or other investigation consists of the individuals or events that are studied?


Read this paragraph and choose the correct option from the provided answers:

The sample in an experiment or other investigation consists of the individuals or events that are studied. Typically, the sample is much smaller than all such individuals or events that exist in the world. Whether the results based on the sample are true in general cannot be known for certain. However, the larger the sample is, the more likely it is that the results are generally true. Similarly, the more times that an experiment is repeated and the same results obtained, the more likely the results are valid. This is why scientific experiments should always be repeated.

 Choices:

- hypothesis

- experimental control

- independent variable

- sample


A:
sample
