Sample representativeness

Sample representativeness refers to how well a small group (sample) reflects the larger group (population) from which it is drawn. For example, if you want to understand the general opinions of a city's residents, surveying a mix of ages, genders, and backgrounds is crucial. This ensures that the results you gather are more likely to represent the views of the entire population. If the sample is skewed—like only surveying young people—the findings may not accurately reflect the broader community's perspectives, leading to misleading conclusions.
