A representative sample is a subset of a population that accurately reflects the characteristics, traits, and diversity of the larger group from which it is drawn. This type of sample is crucial in research, surveys, and statistical analyses because it allows researchers to make generalizations about the entire population based on the findings from the sample.
Key features of a representative sample include:
1. **Diversity**: It should include a variety of participants that capture the different segments of the population, such as age, gender, ethnicity, socio-economic status, and other relevant factors.
2. **Random Selection**: Often, representative samples are obtained through random sampling methods. This helps minimize biases and ensures that every member of the population has an equal chance of being included.
3. **Size**: While there is no one-size-fits-all answer for sample size, larger samples can generally provide more accurate representations of the population.
4. **Minimized Bias**: Steps should be taken to avoid selection bias, where certain members of the population are more likely to be included in the sample than others, which can skew the results.
In summary, a representative sample is essential for obtaining reliable data and ensuring that research findings can be generalized to the broader population.

The option that best describes a representative sample is:
**C. a small quantity that accurately represents a large group.**
This definition captures the essence of what a representative sample is: a smaller subset that reflects the characteristics and diversity of a larger population, allowing for valid conclusions and generalizations about that population.
